python3-m2crypto: avoid host contamination for swig

If the version of libssl-dev is not match the version of libssl on the
build machine, it fails to compile SWIG/_m2crypto_wrap.c which is
created by swig for python3-m2crypto-native:

| SWIG/_m2crypto_wrap.c:9757:19: error: dereferencing pointer to
   incomplete type 'struct stack_st'
|   if (arg1) (arg1)->num = arg2;
|                   ^~

But it works if no libssl-dev installed on the build machine.

Export STAGING_DIR to make existing patch
0001-setup.py-link-in-sysroot-not-in-host-directories.patch work. And
filter out '/usr/inlucde' from include pathes of swig.
