pjsip_configuration: Show actual dtls_verify config.

Rather than merely showing

dtls_verify : Yes/No

in pjsip show endpoint xxx it will now be shown what exactly is being
checked, ie, one of:

dtls_verify : No
dtls_verify : Fingerprint
dtls_verify : Certificate
dtls_verify : Yes

Where Yes implies both Fingerprint and Certificate.
