As noticed by David Gilbert, commit 6053a86 'kvmclock: reduce kvmclock
differences on migration' added 'x-mach-use-reliable-get-clock' and a
compatibility entry that turns it off; however it got merged after 2.8.0
was released but the entry has gone into PC_COMPAT_2_7 where it should
have gone into PC_COMPAT_2_8.
Fix it by moving the entry to PC_COMPAT_2_8.
