  Fix a failure in bio_dgram_test on the NonStop platform

The size of the datagram header is significantly larger that we might
expect on NonStop (probably driven by sizeof(BIO_ADDR)). We adjust the
size of the default buffer to take into account the header size and the
mtu.

Fixes #22013

  -----------
  Further fix in bio_dgram_test for BIO_s_dgram_mem()

When setting an explicit buffer size using BIO_s_dgram_mem() make sure we
take into account the size of the header (which may be large on NonStop)
