Support Arch Linux for required dependency install

[henrychoi7]

Since I'm using Arch Linux for uftrace, is it okay to add support for the dependency install in misc/install-deps.sh? I've already added few lines, tested the installation and it worked fine on running kernel 5.2.14-arch2-1-ARCH. I also separated the capstone in case of old distros. (#833)

Where I'm trying to add it:

uftrace/misc/install-deps.sh

Line 25 in 29b5335

*) # we can add more install command for each distros.

Sure. Please go ahead. @namhyung also uses Arch Linux by the way.

Thank you. I'll create a new PR for this issue later on.

@honggyukim not anymore :(

@henrychoi7 please do!

[honggyukim]

@namhyung I didn't know that. I'm just wondering about your new distro. :)

[namhyung]

Well, I'm using Ubuntu now...

[honggyukim]

Thanks. We now have only Ubuntu, so may have to care more about other distros then.

No pull request yet? I could add arch linux dependencies if you are busy.

@gonapps Thanks for your passion, but I think you don't have to make him hurry :)

@gonapps Sorry about the delay. Please let me know if anything goes wrong.
