Subject: [PATCH 7/7] signal.h: add new sa_flags from linux v5.11

see

  linux commit a54f0dfda754c5cecc89a14dab68a3edc1e497b5
  signal: define the SA_UNSUPPORTED bit in sa_flags

  linux commit 6ac05e832a9e96f9b1c42a8917cdd317d7b6c8fa
  signal: define the SA_EXPOSE_TAGBITS bit in sa_flags

Note: SA_ is in the posix reserved namespace so these linux specific flags
can be exposed when compiling for posix.
