Remove the use of lbolt from the VFS syncer.
It seems we only use `lbolt' inside the VFS syncer and the TTY layer
now. Because I'm planning to replace the TTY layer next month, there's
no reason to keep `lbolt' if it's only used in a single thread inside
the kernel.
Because the syncer code wanted to wake up the syncer thread before the
timeout, it called sleepq_remove(). Because we now just use a condvar(9)
with a timeout value of `hz', we can wake it up using cv_broadcast()
without waking up any unrelated threads.
