Escaped spaces is supported, so remove the extra filtering of the
isolabel on PPC so that it uses the same form as the other arches.
eg. inst.stage2=hd:LABEL=RHEL-7.7\x20Server.ppc64le for an iso with a
label of 'RHEL-7.7 Server.ppc64le'

This adds a new livemedia-creator argument, --extra-boot-args, which can
be used to add arguments to the kernel command-line in the templates.
Resolves: rhbz#1689314
With these templates if a package has installed files in
/usr/share/lorax/product or /usr/share/lorax/updates/ they will be used
to create product.img and/or updates.img which will be included in the
images/ directory of the iso and of the final output tree.
These can be used to customize the installation environment or provide
updates. See README.product for current documentation.

live media isn't exactly the same as the Anaconda install media. Right
now this amounts to needing a root= cmdline argument but in the future
there may be other differences.
This also reverts 5437557846 on the new copies of the templates.
