tools headers uapi: Sync prctl.h with the kernel sources

To get the changes in ba8308856564 ("arm64: add prctl control for
resetting ptrauth keys"), that introduce a prctl with a name that needs
to be catch by the prctl cmd table generator, which will be done in the
next cset.

To get the changes in:

  8d19f1c8e193 ("prctl: PR_{G,S}ET_IO_FLUSHER to support controlling memory reclaim")

Which ends up having this effect in tooling, i.e. the addition of the
support to those prctl's options:
