avcodec/pngdec: use 8-bit sBIT cap for indexed PNGs per spec
The PNG specification[1] says that sBIT entries must be at most the bit
depth specified in IHDR, unless the PNG is indexed-color, in which case
sBIT must be between 1 and 8. We should not reject valid sBITs on PNGs
with indexed color.

Regression since 84b454935fae2633a8a5dd075e22393f3e8f932f.
