main/libc0.9.32: reorganize patches

We keep track of our patches in git now:
http://git.alpinelinux.org/cgit/uClibc-alpine

This is so its easier to keep track of upstream and make sure that
our patches are upstreamed.

we also bump pkgrel so we make sure we get the patches tested properly

+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Otherwise other threads can leave malloc state locked, and the child
+will hang indefinitely if it tries to malloc something.
