Kernel+LibC: Remove sys$donate()
This was an old SerenityOS-specific syscall for donating the remainder of the calling thread's time-slice to another thread within the same process. Now that Threading::Lock uses a pthread_mutex_t internally, we no longer need this syscall, which allows us to get rid of a surprising amount of unnecessary scheduler logic. :^)
