Avoid requiring autom4te when it won't necessarily be needed.

Commit 7fd3e43db07 (tests: Allow environment specified autom4te.) added a
requirement for Autom4te without anyone noticing it in advance.  This
caused a build failure in the XenServer DDK, which doesn't have Autom4te.
Since Autom4te is only needed if the testsuite is modified, this commit
makes it optional.

(Autom4te is part of Autoconf.)
