The local copy of bits.OnesCount64 was added for compatibility with Go
1.8 and earlier in CL 86477. Go 1.8 is no longer supported and go.mod
requires Go 1.12, so drop the local copy and use bits.OnesCount64.

Implement ParseDirent in x/sys/unix instead of calling
syscall.ParseDirent. The latter uses offsets into syscall.Dirent which
might not be matching unix.Dirent depending on Go version. This is e.g.
the case with of FreeBSD whose Dirent structure was updated for Go 1.12.
This fixes TestDirent and TestGetdirentries on freebsd with Go 1.11

On freebsd 12, the system call for getdirentries writes 64 bits to
*basep, even on 32-bit systems. Accomodate that by providing a uint64
to the system call and copy the base to/from that uint64.
The uint64 seems to be a virtual file offset, so failing if the high
bits are not zero should be fine for reasonable-sized directories.

all other GOOS are using Timespec.
StTimespec and Timespec are the same on ppc but not in ppc64. Therefore,

allow the use of Timespec instead of StTimespec.
