GstShmAllocator: Map/unmap full buffer when padding is added

Damian Hobson-Garcia requested to merge dhobsong/gstreamer:shmallocator_align_alloc into main

When allocating buffers with alignment parameters specified, it may be necessary to overallocate memory to adjust to the requested alignment. Previously the padding length was not included in the mmaped buffer size, leaving unmapped bytes at the end of the buffer. This caused intermittent SEGV faults and valgrind failures when running the wayland_threads example.
