Fixup non-optional use of IO::Socket::IP

Fixup non-optional use of IO::Socket::IP

IO::Socket::IP is an optionally used package in our perl scripts, and a
recent change of mine used it unilaterally, causing breakage on older
perl installations.  Fix it up to use it optionally again, falling back
to IO::Socket::INET when needed.

Fixes #27940
