tests: fix spurious failure with older autoconf

Cherry picked from commit v1.11-1950-gba5a89b of 16-02-2012.

* tests/conffile-leading-dot.test: Relax grepping of 'config.status'
stderr, to cater for older autoconf.  Issue revealed by a failure
with autoconf 2.63 on Cygwin 1.5.25. See also automake bug#11093.
