Fix crashes in lisp_align_free in a build with GC_MCHECK.

 src/gmalloc.c (aligned_alloc): Fix adjustment of size of the
 allocated buffer due to alignment.
 (freehook): If the block to be freed was allocated by
 'aligned_alloc', find its real pointer before calling 'free'.
 (mabort) [emacs]: Call 'emacs_abort', not 'abort', to provide a
 backtrace.

Fixes: debbugs:16901
