Make $*PERL initialization non-lazy

If it *is* lazy, the next commit will break precomp.  I've traced this back
to something being serialized when it shouldn't, or vice-versa (being in the
serialized blob without there being a de-serializer).  This actually generates
an error similar to when we have lazy @*INC initialization.
Str.path marked DEPRECATED

If $*PERL is lazy, then this change will break precomp, and thus panda.
