build: improve p11-kit-proxy symlink handling

 - Current command for creation of the p11-kit-proxy symlink
   uses shell brace expansion that isn't supported by all
   the shells (e.g. FreeBSD's /bin/sh does not support that).
   Replace it with the old-fashioned 'for' loop
 - Match extension of the source and the target, i.e. so links
   to so, dylib links to dylib (previously dylib linked to so)
 - Add an uninstall-local target to clean up the symlink
