swtpm: update to 0.6.1

swtpm no longer depends on Python[1] so the dependencies have been
removed.

"inherit perlnative" has been added due to (in oe-core):
deda455b3c ("bitbake.conf: drop pod2man from hosttools")

Some leftover dependencies have also been removed, ex: tpm-tools
required in the past by swtpm_setup.sh (<0.4.0)[2].
