jconfig.h: Restore MEM_SRCDST_SUPPORTED macro

Browse Source 
That macro has been defined in jconfig.h since libjpeg-turbo 1.3.x, so
it is possible that some downstream software conditions the use of the
jpeg_mem_*() functions on whether MEM_SRCDST_SUPPORTED is defined or
JPEG_LIB_VERSION >= 80 (as libjpeg-turbo 2.1.x and prior did
internally.)
