fix: record the ecwolf pk3 without a hash

Follows dc14ccc56. No pk3 shipped at the ecwolf pin is c011b428: the
ECWolf 1.3, 1.3.1, 1.3.2 and 1.3.3 x64 zips carry 13fe8057, cc10cb70,
d312ebbe and 8f4f0387, the buildbot ECWolf.zip 653f7b37, and
src/libretro/ecwolf_pk3_data.c at 0cccd9a8 embeds a 191995-byte pk3,
1a3fd445. The bundled-identity table records the entry with that proof.
