Avoid upgrade conflict with unchanged effective path

This applies to a case such as when /lib is a symlink to /usr/lib. If a
package is installed which contains /lib/libfoo.so, pacman will complain
if this package is then "fixed" to contain /usr/lib/libfoo.so. Since
these have the same effective path and it exists within the same
package, ignore the conflict.

Fixes FS#30681.
