package/gnuradio: remove patch numbering

commit e37c110 ("package/gnuradio: bump version to 3.10.4.0")
included two numbered patches. Those are generating
"make check-package" warnings.

Fixes:
    make check-package
    package/gnuradio/0001-blocks-Including-missing-vector-in-blockinterleaver.patch:4: generate your patches with 'git format-patch -N'
    package/gnuradio/0002-blocks-blockinterleaving.h-add-missing-cstddef-heade.patch:4: generate your patches with 'git format-patch -N'
