intl-modula2: Fix a build failure on Ubuntu 22.04.

* gettext-runtime/configure.ac: Substitute M2SHLIBEXT.
* gettext-runtime/intl-modula2/Makefile.am (libintl_m2_la_LDFLAGS): Attempt
harder to find the libm2pim library.

+# - In distros, either libm2pim.so may work, or m2/m2pim/libm2pim.so, depending
