[Libguestfs] [PATCH 3/5] build: Add Makefile.common, ensure libguestfs.la is built when required



This patch adds a top level Makefile.common and includes it almost everywhere.
It is not included in directories which aren't directly related to the top level
build, for example the daemon.

The force target moves into the new file. It also includes a new rule to rebuild
libguestfs.la automatically as required.
