CREDITS: fix generation in out of tree builds

The {...} code changes the working dir with `cd`, but the commands outside
of that block expects to be in the original dir.  Change to a subshell so
the path outside of this block remains unchanged.

* Makefile.am ($(srcdir)/CREDITS): Change {...} to (...).
