[release-branch.go1.19] net: reenable SRV tests with _ldap._tcp.google.com 

TestLookupDotsWithRemoteSource and TestLookupGoogleSRV
were disabled because they look up the no-longer-present
SRV record for _xmpp-server._tcp.google.com.

Change the tests to look for _ldap._tcp.google.com and
reenable them.

For #56708.
Fixes #56712.
