Default Set serial flag when encountering console argument (#823861)

Short answer: ACK!

There was some further discussion on IRC. For the record:

For master I'd like to remove 'flags.serial' and 'flags.virtpconsole'
entirely - their meanings/uses are vague and confusing. If you want to
check/set text mode, check opts.display_mode; if you want to check what
type of console is in use, check the "console=XXX" boot arg(s).

For F17, there are a few places outside of bootloader.py that change
behavior if 'flags.serial' is set, but as far as we can tell it's all
totally harmless.

Actually, anaconda parses the boot args itself - see
anaconda_optparse.py for the details, but basically it
reads /proc/cmdline, /run/initramfs/etc/cmdline,
/run/initramfs/etc/cmdline.d/*.conf, and /etc/cmdline and sets options
accordingly.

So a kernel arg named "nofb" or "inst.nofb" is the same as passing
"--nofb" to anaconda, and "xdriver=vesa" is the same as
"--xdriver=vesa".
