rGfaa6aa7723aa: tcp: remove CTLFLAG_NEEDGIANT from sysctl(9) handlers related to timers

Summary

They all just modify a global word sized variable via
sysctl_msec_to_ticks(), which is wrapper around sysctl_handle_int().
Note, they all were marked with CTLFLAG_NEEDGIANT merely because it was
not obvious whether they are mpsafe or not.
