Run sysctl -a during the test suite so that KASAN/KMSAN have a chance to
catch something.

sysctl: Teach sysctl to attach and run itself in a jail2025-01-30T18:20:41ZZhenlei Huangzlei@FreeBSD.org2025-01-30T18:20:41Zurn:sha1:08aa7128dea4d14811ae4a0225d7c678869cfe62
This allows the parent jail to retrieve or set kernel state when child
does not have sysctl(8) installed (e.g. light weighted OCI containers
or slim jails).
This is especially useful when manipulating jail prison or vnet sysctls.
For example, `sysctl -j foo -Ja` or `sysctl -j foo net.fibs=2`.

Let the caller open the file and pass in the file handler. This can
benefit an upcoming change so that we will have cleaner logic.
No functional change intended.

So users do not have to contact the source code to tell whether a
variable is a jail prison / vnet one or not.
