pygrub: Specify -rpath LIBEXEC_LIB when building fsimage.so

If LIBEXEC_LIB is not on the default linker search path, the python
fsimage.so module fails to find libfsimage.so.

Add the relevant directory to the rpath explicitly.

(This situation occurs in the Debian package, where
--with-libexec-libdir is used to put each Xen version's libraries and
utilities in their own directory, to allow them to be coinstalled.)
