use _alpm_access in a few more places for increased debugging info

pacman -U <pkg> returns a bogus "could not find or read package" if the
file is on a fuse file system that doesn't allow root access. Debug
output isn't very helpful here either so we should log why the access
check failed.

The other 2 checks already log something when failing so logging a more
specific error won't hurt either.
