Bump BlinkGCPlugin version to 11 to force redownload of Clang 216630

When 216630 was rolled in, there was one roll that got reverted,
and then we re-built packages for the next one. However, some devs
and maybe bots who didn't sync to the revert got stuck with the old
binaries which would now mismatch against goma's checksum.

No behavior change.
