libc/syscalls: Add sbrk implementation
The sbrk implementation in newlib's nosys library does not do any bounds
checking to make sure the allocated memory stays within the heap:
https://sourceware.org/git/?p=newlib-cygwin.git;a=blob;f=libgloss/libnosys/sbrk.c
This version checks for both overflow and underflow.
