configure: move malloc_trim/tcmalloc/jemalloc to meson
Because LIBS is not used anymore, tcmalloc/jemalloc does
not work with binaries whose description is in Meson.
The fix is simply to move them to Meson too.
For consistency with other configure options, specifying
--enable-malloc-trim together with --enable-{tc,je}malloc
becomes a fatal error.
