cpan-base: Add vardepvalue to get_perl_version function

* without this bitbake -S perf shows following error:
  ERROR: Bitbake's cached basehash does not match the one we just generated
    (/OE/oe-core/meta/recipes-kernel/perf/perf.bb.do_package)!
  if you run it twice, once without perl in sysroot and once with perl
  already built
