configure: fix --custom-allocator

The custom-allocator logic has been completely defunct since a while,
since nothing depends on those targets, they never get used.
This updates jemalloc to pkg-config, adds the fallback option for
potential arbitrary allocators, and finally actually adds the libraries
to LDFLAGS.
