[cmake] Don't create installation directories that already exist

Browse source 
fish's cmake install routines were attempting to create system
directories that already existed, an operation for which the permissions
to do so may not be available (e.g. /usr/local/share/pkgconfig)

This commit first checks if a directory exists before creating it.
