compat-3.3: include module.h

compat/compat-3.3.c:172:1: warning: data definition has no type or storage class [enabled by default]
compat/compat-3.3.c:172:1: warning: type defaults to ‘int’ in declaration of ‘EXPORT_SYMBOL_GPL’ [-Wimplicit-int]
compat/compat-3.3.c:172:1: warning: parameter names (without types) in function declaration [enabled by default]

In newer kernels we should include export.h, but
not all kernels have that so use module.h which
always works.
