Update FRC_10_8.2.4_View_C.pdf entry in the suppression list

CL [1] fixed the Skia rendering issue for FRC_10_8.2.4_View_C.pdf but
caused crash for SkiaPaths due to unclear premultiplied /
unpremultiplied status of a bitmap.

Currently there are unresolved conflicts in the premultiplied /
unpremultiplied statuses for Skia and SkiaPaths process. We prefer
increasing the Skia test coverage and suppressing the failed SkiaPaths
tests first since SkiaPaths will eventually be removed.

Therefore enable FRC_10_8.2.4_View_C.pdf for Skia and suppress it for
SkiaPaths.
