[PATCH v2] libpoke: fix building pvm.jitter on windows

[Hannes Domani]

When trying to build libpoke on windows, you get the following error:

../../../poke.git/libpoke/pvm.jitter: In function 'pvm_execute_or_initialize':
../../../poke.git/libpoke/pvm.jitter:227:37: error: 
'pvm_specialized_instruction_opcode_rpl_raise' undeclared (first use in this 
function); did you mean 'pvm_specialized_instruction_opcode_raise'?

It's because gnulib replaces raise with rpl_raise in gl-libpoke/signal.h:

 #define raise rpl_raise

As far as I can tell, raise is actually not used by libpoke, so this just
removes the define in the generated header.

        * libpoke/pvm.jitter: Undef raise on windows.
