Makefile: Suffix libguilexapian with effective Guile version number.

We need to distinguish between libguilexapian built for different
versions of Guile.

* Makefile.am (lib_LTLIBRARIES): Replace libguilexapian.la with
libguilexapian-@GUILE_EFFECTIVE_VERSION@.la.
(libguilexapian_la_SOURCES): Rename to
libguilexapian_@GUILE_EFFECTIVE_VERSION@_la_SOURCES.
(libguilexapian_la_CXXFLAGS): Rename to
libguilexapian_@GUILE_EFFECTIVE_VERSION@_la_CXXFLAGS.
(libguilexapian_la_LDFLAGS): Rename to
libguilexapian_@GUILE_EFFECTIVE_VERSION@_la_LDFLAGS.
(xapian.i): Substitute @GUILE_EFFECTIVE_VERSION@.
(xapian/xapian.go): Depend on
libguilexapian-@GUILE_EFFECTIVE_VERSION@.la instead of
libguilexapian.la.
* xapian.i.in: Load libguilexapian-@GUILE_EFFECTIVE_VERSION@.la
instead of libguilexapian.la.
