malloc_trim.3: Remove mention of free() call 

'malloc_trim' was and is never called from the 'free' function.
see related bug in glibc tracker:
https://sourceware.org/bugzilla/show_bug.cgi?id=2531. or
'__int_free' function. Only the top part of the heap is trimmed
after some calls to 'free', which is different from 'malloc_trim'
which also releases memory in between chunks from all the
arenas/heaps.
