Mateusz Piotrowski 9a593520b5 Add missing types to the sysctl(9) manual page
Update the diff to include other missing sysctl types found in sysctl.h.

Some of these sysctls are already documented in other pages (e.g counter(9)
and ZONE(9)), but they should at least be mentioned here for completeness.

This patch now documents all of the following:
- SYSCTL_BOOL/SYSCTL_ADD_BOOL
- SYSCTL_COUNTER_U64/SYSCTL_ADD_COUNTER_U64
- SYSCTL_COUNTER_U64_ARRAY/SYSCTL_ADD_COUNTER_U64_ARRAY
- SYSCTL_SBINTIME_MSEC/SYSCTL_ADD_SBINTIME_MSEC
- SYSCTL_SBINTIME_USEC/SYSCTL_ADD_SBINTIME_USEC
- SYSCTL_UMA_CUR/SYSCTL_ADD_UMA_CUR
- SYSCTL_UMA_MAX/SYSCTL_ADD_UMA_MAX
