pcb: remove noarch.
https://github.com/void-linux/void-packages/pull/25512

Description:
also note that i686 tests are borked. Didn't fix because:

1. I have no idea how `pcb` works, or ghostscript, or any of the weird formats it uses.
2. It's malformed output not a segfault/crash and I didn't feel like digging into obscure stuff like that, I'll leave that to someone more experienced.

For some reason it needed texlive to build??
