[PATCH] vc-list-files: make the last-resort awk code more portable

[Jim Meyering]

FYI, I've just pushed this, to avoid a failure
of tests/test-vc-list-files-cvs.sh on opensolaris.

Subject: [PATCH] vc-list-files: make the last-resort awk code more portable

* build-aux/vc-list-files: Don't rely on awk's "sub" command.
/bin/awk from OpenSolaris 11's SUNWesu version 2008.03.22.10.56
does not support it.
