util: Expand the valgrind suppressions file to the entire libpython.
Suppress any valgrind error from *anywhere* in the libpython library.
There are ***many*** false positives in the python library, making the
output of valgrind almost useless without lots of suppressions. Rather
than suppress each error piecemeal, we can suppress any error which
originates in libpython to cover them all.
There will now be corner cases where a bug in gem5 causes some sort of
illegal access, etc, within the python library itself, but these sorts
of interactions/errors should be very rare. Suppressing the fountain of
false positives coming from libpython makes valgrind useable in general,
which IMO is a very worthwhile tradeoff.
