perl plugin: Work around a compiler warning on FreeBSD.

On FreeBSD, PERL_SYS_INIT3 expands to some expression which triggers a "value
computed is not used" warning by gcc. By telling the compiler to ignore this
value, we can work around this issue. In the long run, this should imho be
fixed in Perl though.
