Andrew Gregory 0fd8455c66 unlink_file: strip trailing slashes 
If the user replaces a directory with a symlink, libalpm would get
confused because the trailing slash causes system calls to resolve the
symlink.  This leads to errors and a misleading message during upgrades.
Even though libalpm does not support this, it should not be giving
misleading errors.

Also adds an overflow check.

Fixes FS#51377
