avcodec/x86/mpeg4videodsp: Fix build failure without x86asm
Since ba793127c413ba27386cea4c23db021b1eaa8d56,
the x86 mpeg4videodsp code uses ff_emulated_edge_mc_sse2()
instead of ff_emulated_edge_mc_8. This leads to linker errors
when x86asm is disabled. Fix this by also falling back to ff_gmc_c()
in case edge emulation is needed with external SSE2 being unavailable.

An alternative is to go back to ff_emulated_edge_mc_8(), but this
would readd the uglyness to videodsp for a niche case.
