bitbake: codeparser: Allow empty functions

The main parser and other code copes with empty python functions but
the python codeparser does not. Fix this to avoid errors with code like:

python do_build () {
}

which currently results in the obtuse:
"Failure expanding variable do_build: IndexError: string index out of range"

[YOCTO #7829]
