linux: Retry VT ioctls while errno == EINTR
When the smart scheduler is enabled, the VT ioctls (particularly
VT_WAITACTIVE) can be interrupted by the smart scheduler's SIGALRMs.
Previously, this caused the server to immediately continue on to
ScreenInit, almost certainly causing a crash or failure because the X
server that owned the VT hadn't finished cleaning up. As of commit
7ee965a300c9eddcc1acacf9414cfe3e589222a8, it causes a FatalError
instead.
Retrying the ioctl as long as it fails with errno == EINTR fixes the
problem and allows server regenerations to trigger VT switches that
actually succeed.
