tmux >= 3.1b no longer needs sys/queue.h, other headers form
bsd-compat-headers are not need either.

Busybox needs pod2man from the perl package to build the man page.
Unfortunately, if pod2man is not installed this only causes a warning,
not an error.

Resolves #11443

Before this change:

    $ dabuild sh
    $ sudo apk add subunit >/dev/null && subunit-stats --help
    env: can't execute 'python': No such file or directory

After this change:

    $ dabuild sh
    $ sudo apk add subunit >/dev/null && subunit-stats --help
    Usage: subunit-stats [options]
    ✂

add the dependencies of subpackages to makedepends so those gets built
before bind.

fixes #11462

segfaults in the test suite indicate something is broken. Upstream
guesses it's either pysqlite or python.
