tests: fix unit and module tests broken by OMNeT++ 6.4 method call logging

OMNeT++ 6.4 unconditionally prints "Method call" lines to the simulation
output whenever a direct method call crosses module boundaries. These
lines are now interleaved with the regular log output, causing %contains
and %contains-regex checks in several tests to fail.

Fix the affected tests by adding a %subst directive that strips these
lines before the output is matched against the expected patterns:

  %subst: /^Method call [^\n]*\n//m

For tests that use a custom cmdenv-log-prefix ("At %ts %N: "), the
method call lines carry that prefix, so a different pattern is used:

  %subst: /^At \S+ \S+: Method call [^\n]*\n//m

Fixed unit tests (3):
  Clock_OscillatorCompensation_4, _5, _6

Fixed module tests (13):
  pingapp_lifecycle_1..8, EtherHost_lifecycle,
  IPv4_ICMPerror_NoProtocol, ExternalProcess_3,
  PacketGate_1, PriorityScheduler_1
