[PATCH] bootstrap: don't exit 0 upon gnulib-tool failure

[Jim Meyering]

I ran (syncsub, commit, etc.), ./bootstrap && ./configure && make in
coreutils, expecting the regcomp.c changes to cause the bootstrap to fail.
I got these diagnostics:

  gnulib/gnulib-tool: *** patch file gl/lib/regcomp.c.diff didn't apply cleanly
  gnulib/gnulib-tool: *** Stop.

but they scrolled by as configure and make ran.
Oops.  Here's the fix:
