Cwd.xs: avoid blib better while building
RT # 125603
There's an old line in Cwd's Makefile.PL:
BEGIN { @INC = grep {!/blib/} @INC }
This was added 12 years ago to solve a problem with a static perl and
building a newer Cwd (but no-one's quite sure what *exactly* the issue was
any more).
However, this breaks building perl under a directory that has 'blib'
in the pathname. This commit estricts the grep to just exclusing exactly
blib/lib and blib/arch.
This should hopefully still workaround the static build issue, while no
longer breaking perl builds.
