[CFI] Require LLD for ProtectedMemory on Linux

gold, used to link on Android and CrOs, does not create a read-only
segment. It places read-only sections, like the one for ProtectedMemory,
in the read-execute segment and could cause executable pages to be
marked read-only. Workaround this by requiring the use of lld on Linux
builds while those platforms are ported to lld.
