Currently, ClocksPerSec is determined by exec'ing getconf in func init,
i.e. on startup of every program importing the package. getconf might
not be present on some systems or is not executable by the current user.
To avoid this hard to control dependency, use the
github.com/tklauser/go-sysconf package which implements sysconf(3)
entirely in Go without cgo. The package is supported on all platforms
currently supported by the cpu and v3/cpu package of gopsutil.
All BSDs use the same implementation to get BootTime{,WithContext} and
Uptime{,WithContext} based on the kern.boottime sysctl. Move this
implementation to a separate host/host_bsd.go file shared by darwin,
freebsd and openbsd. Also use SysctlTimeval to get
the boot time directly as a type Timeval instead of manually
extracting it using package unsafe. It will also allow for easier reuse
to support package host on e.g. Dragonfly BSD or NetBSD.
This requires updating the golang.org/x/sys/unix dependency to the
latest revision.

There was a breaking change in upstream golang.org/x/sys/unix which
changed the type of some Statvfs members, see #853. As it looks like
this change won't be reverted, adjust gopsutil to work with it and allow
to build against the latest version of x/sys/unix.
All functions used from github.com/shirou/w32 are also available from
golang.org/x/sys/windows which is already used in other places. Convert
the remaining usages to use the functions from x/sys/windows.
