build: add checks for openssl configure options

Currently it is possible to configure using --without-ssl and
--shared-openssl/--openssl-no-asm/openssl-fips without an error
occuring.

The commit add check for these combinations:

$ ./configure --without-ssl --shared-openssl
Error: --without-ssl is incompatible with --shared-openssl

$ ./configure --without-ssl --openssl-no-asm
Error: --without-ssl is incompatible with --openssl-no-asm

$ ./configure --without-ssl --openssl-fips=dummy
Error: --without-ssl is incompatible with --openssl-fips
