autotools: add a new autoconf variable: ${gajim_srcdir}.

It expanded version is GAJIM_SRCDIR.

It indicate where pyfiles will be installed (for now: PREFIX/share/gajim/src).

simplify src/Makefile.am by using nobase_ and dist_ prefix.
nobase_ allows hiearchical installation instead of flat directory
installation.
