CL 250437 removed all SYS_* consts on darwin as direct syscalls are no
longer supported on this platform. However, some external packages (e.g.
github.com/shirou/gopsutil) still seem to rely on SYS___SYSCTL being
defined to implement their own sysctl wrappers. Re-add SYS___SYSCTL to
avoid breaking these packages.

CL 250437 broke the build with Go 1.12 on darwin, due to
SYS_GETDIRENTRIES64 being removed. However, this is still needed to
implement Getdirentries for Go 1.12 because it does not provide
syscall_syscallPtr for fdopendir. Thus, add _SYS_GETDIRENTRIES64 as an
unexported const.

Since CL 250437 this package no longer supports non-libc, direct
syscalls. Thus the corresponding special cases can be removed from
the generating mksyscall.go program.

Go 1.12 and newer are using libSystem for syscalls on darwin.
Go 1.11 is the last release to use direct syscalls. It hasn't been
supported since the release of Go 1.13 in September 2019, so drop
support for direct syscalls.

This was the intention from the start, but due to a logic error in the
handling of slices the implementation only handled minimum 8 character
strings.
This commit also improves the tests.

Some systems (e.g. the linux-arm and linux-arm64-packet builders) return
EPERM instead of ENOSYS on unimplemented syscalls. Fall back to the
existing glibc-like implementation in Faccessat in this case as well.
This fixes tests on the linux-arm and linux-arm64-packet builders after
CL 246537.

These are Linux-specific system calls for efficiently reading and
writing memory in foreign processes.
A new RemoteIovec type is added for use in these wrappers, as Iovec's
Base field is a pointer, and creating invalid pointers is invalid in
Go.

CL 223698 changed the types of the Fstypename, Mntfromname and Mntonname
fields of type Statfs_t on freebsd/{386,amd64,arm64}, but didn't do so
on freebsd/arm. Since reverting that change now would probably cause
more harm than good, at least make the type consistent on all supported
freebsd/$GOARCH combinations.

The regression test included in this change verifies that the type is,
in fact, equivalent, while allowing the actual header definitions to
avoid importing the (relatively heavy) "reflect" package itself.
This change is loosely based on Keyan Pishdadian's draft in CL 230557.
