Clemens Lang e3dbb5a483 Disable FIPS mode
FIPS mode does not work on RHEL-9 since the selftests fail. OpenSSL 1.1
in FIPS mode will not be supported on RHEL-9, so disable it. Apply
a minimal patch that keeps the library in the same state otherwise to
avoid problems with binary compatibility.

Disable FIPS mode
FIPS mode is not supported for compat-openssl11. Apply a minimal patch
that will reject explicit enabling of FIPS mode and disable automatic
activation of FIPS mode.
To avoid regressions, keep the rest of the library as it was.
