Subject: config: Remove CONFIGURE_POSIX_HAS_OWN_INIT_THREAD_TABLE

The CONFIGURE_HAS_OWN_INIT_TASK_TABLE and
CONFIGURE_POSIX_HAS_OWN_INIT_THREAD_TABLE are the last *_HAS_OWN_*
configuration options.  These two options are probably unused, see also:

* https://lists.rtems.org/pipermail/users/2019-April/033129.html

* https://lists.rtems.org/pipermail/users/2019-April/033130.html

Removing them simplifies the configuration. If there is a real user need
which shows up after the removal, we can resurrect them on demand.

Using CONFIGURE_POSIX_HAS_OWN_INIT_THREAD_TABLE would have required the
use of the undocumented CONFIGURE_POSIX_INIT_THREAD_TABLE_NAME and
CONFIGURE_POSIX_INIT_THREAD_TABLE_SIZE configuration options.

Update #3874.
