crypto: Remove incorrect configure check for FIPS_mode_set

[sverker]

Fix #8271

• FIPS_mode_set does not exists since OpenSSL 3.x

• The configure check with AC_CHECK_FUNC for FIPS_mode_set succeeds anyway on Linux as compiler accepts implicit declaration (with only a warning) and linker accepts undefined symbols as we build a shared lib.

• Checking for FIPS_mode_set was pointless as it was available even for non-fips builds of OpenSSL 1.x

On MacOS however, the check "works" and thereby hinders building Erlang/OTP with --enabled-fips for OpenSSL 3.x.
