[PATCH] bootstrap: accommodate older libtool

[Eric Blake]

RHEL 5 still ships with libtool 1.5.22, where libtoolize lacks the
--install option but has that behavior by default.  And gnulib's
DEPENDENCIES file states that we still support that old of libtool
as our minimum version.

* build-aux/bootstrap (use_libtool): Cater to libtool 1.5.22.
Reported by Daniel P. Berrange.

I tested that this fixed the libvirt-on-RHEL5 issue (I hadn't seen
it earlier because I had been doing incremental builds, rather than
fresh clones, so the files were already installed in my tree).
