bootstrap: avoid failure when there is no .gitmodules file

": ${gnulib_path=gnulib}" fails to set $gnulib_path when that variable
has been assigned to, even when its value is the empty string.
* build-aux/bootstrap (gnulib_path): Test explicitly for an empty
"$gnulib_path", rather than using ${gnulib_path=gnulib}.
Reported by John W. Eaton <jwe@gnu.org>.
