Gilles Peskine 6667a78c9b Add test for mbedtls_net_poll beyond FD_SETSIZE
mbedtls_net_poll() and mbedtls_net_recv_timeout() rely on select(),
which represents sets of file descriptors through the fd_set type.
This type cannot hold file descriptors larger than FD_SETSIZE. Make
sure that these functions identify this failure code.

Without a proper range check of the file descriptor in the
mbedtls_net_xxx function, this test fails when running with UBSan:
```
net_poll beyond FD_SETSIZE ........................................ source/library/net_sockets.c:482:9: runtime error: index 16 out of bounds for type '__fd_mask [16]'
SUMMARY: UndefinedBehaviorSanitizer: undefined-behavior source/library/net_sockets.c:482:9 in
```
This is a non-regression test for
https://github.com/ARMmbed/mbedtls/issues/4169 .

The implementation of this test is specific to Unix-like platforms.
