trafficserver: Fix installation with INSTALL_BASE
trafficserver: Fix installation with INSTALL_BASE

trafficserver tries to install some perl modules into it's cellar, which
fails if the perl INSTALL_BASE is set through the PERL_MM_OPT env var
with the following error:

> Only one of PREFIX or INSTALL_BASE can be given.  Not both.

INSTALL_BASE is set in the environment variable PERL_MM_OPT if the user
has gone through the CPAN setup wizard and chose to install perl modules
to $HOME/perl5. This fix unsets the environment var, so that the perl
Makefile.pl can install into the PREFIX set to the cellar.

Closes #45091.
