Fix false "TLS: NOT LOADED" startup banner in Easy Asterisk entrypoint

pjsip show transports was checked once, immediately after "core show
version" first responded — but res_pjsip can take a moment longer to
finish binding its transports, so the check would sometimes read an
empty transport list and print "NOT LOADED" even though transport-tls
came up correctly a second later (confirmed live: TLS SIP traffic on
5061 in the container logs right after the misleading banner).

Poll for up to 10s instead of checking once, matching the existing
core-show-version wait pattern further up the same script.
