openswan: fix older gcc build failure 

Older gcc versions (< 4.4) don't accept cpp as -Werror / -Wno-error
parameters.
Disable it since it's not yet a default with any version and we don't do
-Werror by default. Fixes:

Kill -Wno-error=cpp, old(ish) gcc versions (< 4.4) don't like it and we still
got 4.3.x available for internal toolchains.
