autoconf: Fix the --disable-* case for the AC_ARG_ENABLE macros
--disable-smpp would actually not disable SMPP but enable it. Correct
it for all usages of AC_ARG_ENABLE.
Move the unconditional invocation of PKG_CHECK_MODULES before the
conditional one to make it work as the pkg-config m4 macro appears
to expand the first usage differently and searches for the pkg-config
exuable.
Use "$enableval" to see if the feature should be enabled or disabled
and then search for the module afterwards.
