configure: use pkg-config for libmp3lame when available
LAME 3.101 adds pkg-config support, generating and installing lame.pc.
Its autotools build also replaces the bundled mpglib decoder with
external libmpg123. Static libmp3lame builds with decoding support
therefore require additional libraries when linking.
The existing check links only against libmp3lame and libm, ignoring
pkg-config metadata and failing with undefined mpg123_* references.
Try pkg-config first to obtain the compiler and linker flags, honoring
the configured pkg-config flags for static dependencies. Keep the
existing library check as a fallback for older LAME releases and other
installations without usable pkg-config metadata.
