TinyCrypt Test: Expand scope of compatibility testing for TinyCrypt

Previously, the TinyCrypt all.sh test restricted the run of compat.sh
to DTLS 1.2 and listed a few explicit ciphersuites.

This commit widens the scope of the test by testing any ciphersuite
based on ECDHE-ECDSA, regardless of TLS/DTLS or the particular version.

Further, it doesn't exclude SHA-384 as done previously.
