Update skarnet base libraries

[kurth4cker]

Testing the changes

• I tested the changes in this PR: briefly
  I'm using s6 suite instead of runit daily. They didn't break. Just works. But I don't use revbumped software.

Local build testing

• I built this PR locally for my native architecture, (x86_64-glibc)

I plan to update all skarnet stack. This is base.

Thank you, but lets slow down. lemme update s6 stuff and I'll add s6-frontend pkg in next week.

But I don't use revbumped software.
