[ci] detect non-default dynamic symbols in check_dynamic_dependencies.py

[jameslamb]

While updating #5252 to the new CI image proposed in guolinke/lightgbm-ci-docker#29, I found that the Linux regular and Linux swig jobs were failing with the following.

Traceback (most recent call last):
File "/__w/1/s/helpers/check_dynamic_dependencies.py", line 55, in
check_dependencies(Path(sys.argv[1]).read_text(encoding='utf-8'))
File "/__w/1/s/helpers/check_dynamic_dependencies.py", line 30, in check_dependencies
assert len(versions) > 1
AssertionError

I was able to reproduce this locally in a container too.

how to reproduce this (click me)

docker run --rm -ti \
    -v $PWD/artifacts:/artifacts \
    -e AZURE=true \
    -e BUILD_DIRECTORY=/vsts/lightgbm \
    -e BUILD_SOURCESDIRECTORY=/vsts/lightgbm \

.ci/setup.sh
mkdir $BUILD_DIRECTORY/build
cd $BUILD_DIRECTORY/build
cmake -DUSE_SWIG=ON ..

make -j4

objdump -T $BUILD_DIRECTORY/lib_lightgbm.so > $BUILD_DIRECTORY/objdump.log
objdump -T $BUILD_DIRECTORY/lib_lightgbm_swig.so >> $BUILD_DIRECTORY/objdump.log
python $BUILD_DIRECTORY/helpers/check_dynamic_dependencies.py $BUILD_DIRECTORY/objdump.log

I found that this is happening because helpers/check_dynamic_dependencies.py ignores non-default symbol versions in the output from objdump.

From the objdump docs (link)

-T
Print the dynamic symbol table entries of the file....

...If the version is the default version to be used when resolving unversioned references to the symbol then it's displayed as is, otherwise it's put into parentheses.

In other words, that script ignores versions in objdump -T lib_lightgbm.so output like the following:

0000000000000000      DF *UND*	0000000000000000 (GLIBC_2.2.5) strcpy
0000000000000000      DF *UND*	0000000000000000 (GLIBC_2.2.5) fflush
0000000000000000      DO *UND*	0000000000000000 (GLIBC_2.2.5) stderr
0000000000000000      DF *UND*	0000000000000000 (GLIBC_2.2.5) fprintf
0000000000000000      DF *UND*	0000000000000000 (GLIBC_2.2.5) snprintf
0000000000000000      DF *UND*	0000000000000000 (GLIBC_2.2.5) memmove

Because it expects to only see stuff like this

0000000000000000      DF *UND*	0000000000000000 GLIBC_2.2.5 strcpy
0000000000000000      DF *UND*	0000000000000000 GLIBC_2.2.5 fflush
0000000000000000      DO *UND*	0000000000000000 GLIBC_2.2.5 stderr
0000000000000000      DF *UND*	0000000000000000 GLIBC_2.2.5 fprintf
0000000000000000      DF *UND*	0000000000000000 GLIBC_2.2.5 snprintf
0000000000000000      DF *UND*	0000000000000000 GLIBC_2.2.5 memmove

This PR fixes that.
