Makefile: detect sfml-all pkg-config for SFML 3.1+

SFML 3.1 renamed the pkg-config file from sfml to sfml-all. When
sfml-all is found, use --static --libs to resolve all transitive
dependencies (harfbuzz, mbedtls, libssh2, etc.) rather than relying
on the plain --libs TEMP_LIBS path which misses them.
