Confirm that the "selectable" flag is set before calling the underlying select() API. Also update unit tests to match.

Describe the contribution
On some OS's (notably RTEMS) one must only call select() socket file handles. This is indicated in OSAL via the "selectable" flag on each file handle. The select implementation needs to check this before invoking select().
Also update unit tests to match.
Fix #453
Testing performed
Confirm unit tests passing on relevant platforms
Expected behavior changes
Calls to select APIs on RTEMS where unsupported will return OS_ERR_OPERATION_NOT_SUPPORTED, rather than crashing.
System(s) tested on
Ubuntu 20.04 (native)
RTEMS 4.11 on i686 via QEMU
Additional context
This also affects #377 in that it improves the test, but the functional test still could be better in that it currently only checks for file handles being set, not file handles being unset, after select.
