core/br2-external: properly report unexpected errors
Unextected error in the br2-external script are properly caught, but
they are not reported properly, and we end up in either of two
situations:
- the .br2-external.mk file is not generated, in which case make will
try to find a rule to generate it (because the 'include' directive
tries to generate missing files);
- the .br-external.mk file is generated but does not contain the error
variable, and thus the build might not get interrupted.
We fix that by using a trap on the pseudo ERR signal, to emit the error
variable on unexpected errors.
