[PATCH 09/10] sysctl: ipv4 remove binary sysctl paths where they are broken.

Currently tcp_available_congestion_control does not even
attempt being read from sys_sysctl, and ipfrag_max_dist
while it works allows setting of invalid values using
sys_sysctl.

So just kill the binary sys_sysctl support for these
sysctls.  If the support is not important enough to
test and get right it probably isn't important enough
to keep.
