Get $ENV{PERL5LIB} into a known consistent state under TEST - delete it!

(It doesn't strike me as good that t/TEST and t/harness are inconsistent -
the former runs every test with -MTestInit; the latter sets $ENV{PERL5LIB} to
'../lib'; and on the gripping hand, we have boilerplate in every test to set
@INC. No choice seems ideal.
