malloc: Fix unused internal_memalign warning with mcheck

Browse Source 
When CONFIG_MCHECK_HEAP_PROTECTION is enabled, dlmemalign_impl() calls
dlmalloc_impl() directly since the mcheck wrapper handles alignment.
This leaves internal_memalign() unused, causing a compiler warning.

Guard internal_memalign() with a preprocessor check so it's only
compiled when needed (mcheck disabled or MSPACES enabled).
