Bug 1000994 - Allow specifying SONAME of a shared library in moz.build. r=glandium
Bug 1000994 - Use SONAME to specify soname for libmozgtk & stubs. r=glandium

The current implementation of the solution outlined in bug 6244229
uses LDFLAGS in Makefile.in to specify the SONAME. This patch uses
the new SONAME option in moz.build to do the same, and removes the
LDFLAGS manipulation from Makefile.in.
