update-alternatives: correctly escape PATHs when updating FILES_${PN}
The recently added support for updating FILES based on the file renames
that are happening here is using a regex replace, but failed to
properly escape the search pattern (the full path). This manifests itself
in FILES not being updated as soon as the full path contains any
character that has a special meaning, e.g. '+'.
In other words an original path (alt_target in the code) like
/opt/poky/2.6+snapshot/sysroots/i686-pokysdk-linux/sbin/losetup
can't be matched, and hence we fail to update FILES with the new value,
causing packaging errors.
Fix by using re.escape() on the original path before passing into re.sub()

renaming a file"), or
