Revert "Update Gnulib to v0.1-603-g1d16a7b"

This reverts commit 2d4da30fdefbcdb065d4b1f48f2a77d06f69e3c3.

This Gnulib update was causing failures related to timezones in
stime.c.  I tried to fix it by adopting the time_rz module from gnulib
but that then caused other failures.  We can try again later.
