build: Fix bsdiff Makefile circular dependency

The intended use was to have the .am.inc generated from the .am like the
libglnx one. Without this, make was detecting a circular dependency and
dropping the rule:

  make: Circular bsdiff/Makefile-bsdiff.am.inc <- bsdiff/Makefile-bsdiff.am.inc dependency dropped.

Closes: #1276
