tests defs: one more environment sanitization (corner case)

* tests/defs (am__using_gmake): Initialize.  The `using_gmake'
subroutine was using this variable for caching, but wasn't
initializing it, which could cause problems in the (admittedly
very unlikely) case in which it was pre-existent in the
environment.
