chromes/chrome_restart_request: Don't propagate kUseHDRTransferFunction

crrev.com/c/2276516 added kUseHDRTransferFunction to Chrome's list of
flags upon restart. This is only needed for features that re disabled
by default IIUC, and crrev.com/c/2317569 enabled that feature; adding
a default-enabled-feature there breaks a few Guest mode browser_tests.
This CL removes that propagation.
