* Rename parsePoolObjsetFile to parseLinuxPoolObjsetFile to better reflect
it's scope
* Create a new parseFreeBSDPoolObjsetStats function, to generate a list
of per pool metrics to be queried via sysctl

Use SysctlTimeval from the golang.org/x/sys/unix package to
simplify the implementation of the boottime collector for the BSDs and
allows to build it without cgo.
Tested on macOS 11.6, FreeBSD 13 and OpenBSD 7.

According to the golang docs, the syscall package is deprecated.
https://golang.org/pkg/syscall
This updates collectors to use the x/sys/unix package instead.
Also updates the vendored x/sys/unix module to latest.

* Correct buffer_bytes > INT_MAX on BSD/amd64.
The sysctl vfs.bufspace returns either an int or a long, depending on
the value. Large values of vfs.bufspace will result in error messages
like:
couldn't get meminfo: cannot allocate memory
This will detect the returned data type, and cast appropriately.
* Added explicit length checks per feedback.
* Flatten Value() to make it easier to read.
* Simplify per feedback.
* Fix style.
* Doc updates.
