Description of PR
Summary:
Fixes sonic-net#16436, caused by added BGP check in sonic-net#15936, which doesn't account for T2 BGP time to come up

Approach
What is the motivation for this PR?
Function wait_bgp_sessions timeout is too short for T2, fails in test_mgmt_ipv6_only test suite causing a fixture to error wrongly and not teardown properly leaving TB in bad state without ipv4 mgmt ip

How did you do it?
Increase timeout to 900s from 120s if duthost it is checking is supervisor

How did you verify/test it?
Run locally on T2

See for passing test:

17/01/2025 07:34:39 utilities.wait_until L0153 DEBUG | check_bgp_session_state_all_asics is False, wait 10 seconds and check again
17/01/2025 07:34:49 utilities.wait_until L0135 DEBUG | Time elapsed: 164.073392 seconds
Confirming it needs more than 120 seconds
