* Added ptrace and constants for all freebsdlike and netbsdlike OSs

Provide a symbol for the `ftok` function declared in sys/ipc.h, for completeness and to allow calling `ftok` to generate the key value for `shmat`.

For range-based locking POSIX fcntl locks are needed. This adds the
constants F_RDLCK, F_UNLCK, and F_WRLCK for FreeBSD, NetBSD, OpenBSD,
DragonFlyBSD, and macOS/iOS. Fortunately these values are defined the same across these platforms.

These are necessary for large file support on 32-bit platforms,
following the same pattern as 74825222 ("Add bindings for
-D_FILE_OFFSET_BITS=64").

Remove false support for power and mips.
Fix aarch64 definitions of nlink_t and blksize_t.

The futimes(), lutimes(), mq_timedreceive(), and mq_timedsend()
functions were linking against legacy library symbols that need 32-bit
time_t in structures, resulting in an ABI mismatch with 64-bit time_t.

Looks like Travis has moved on from our old images, so we're forced to
update.
