kernel-install: Don't copy pacman gpg sockets

These should be created in /run but gpg's logic for that is broken
for the root user (it checks for /run/user/0 which will never exist)
so the sockets are created in the gpg home dir (/etc/pacman.d/gnupg)
instead. Let's make sure we don't try to copy those as they cause issues
with cp -R.

Fixes #2547
