[dockers] Rename 'docker-lldp-sv2' to 'docker-lldp' (#4700)
The -sv2 suffix was used to differentiate SNMP Dockers when we transitioned from "SONiCv1" to "SONiCv2", about four years ago. The old Docker materials were removed long ago; there is no need to keep this suffix. Removing it aligns the name with all the other Dockers.

# Current lldpd version has a bug.
# When lldpd starts it is in the pause state by default
# But then it execute 'lldpcli resume' to configure and unpause itself.
# When lldpd execute lldpcli, it doesn't check the return code
# Sometimes lldpcli returns failure, but lldpd doesn't catch it
# and keeps working paused and unconfigured
#
# The fix below addresses the issue.
#
# wait until lldpd started
until [[ -e /var/run/lldpd.socket ]];

# Manually try to resume lldpd, until it's successful
