selftests: forwarding: Suppress grep warnings

Suppress the following grep warnings:

[...]
INFO: # Port group entries configuration tests - (*, G)
TEST: Common port group entries configuration tests (IPv4 (*, G))   [ OK ]
TEST: Common port group entries configuration tests (IPv6 (*, G))   [ OK ]
grep: warning: stray \ before /
grep: warning: stray \ before /
grep: warning: stray \ before /
TEST: IPv4 (*, G) port group entries configuration tests            [ OK ]
grep: warning: stray \ before /
grep: warning: stray \ before /
grep: warning: stray \ before /
TEST: IPv6 (*, G) port group entries configuration tests            [ OK ]
[...]

They do not fail the test, but do clutter the output.
