bootstrap: don't reset config-h.in timestamp newer than configure

Browse Source 
Various autotools rules will compare the timestamps of config-h.in
and configure, and if config-h.in is newer than configure, attempt
to regenerate it.  This breaks `make distcheck` which we need to
produce new releases.  So update config-h.in timestamp, but only
up to the configure file.

The breakage is caught because distcheck makes source dirs read-only
before running.

$ make distcheck
...

make[3]: *** [Makefile:2411: ../../libltdl/configure] Error 1

* bootstrap.conf (libtool_fudge_timestamps): Set config-h.in timestamp
to configure.
