live: Drop patterns-yast-yast2_basis requirement

[g7]

Problem

patterns-yast is not available in SLFO/SLE16.

Solution

Added a requirement for the pattern only when using the openSUSE, openSUSE-PXE, Leap and Leap-PXE profiles.

As suggested by Josef below, dropped it entirely on openSUSE as well as the whole pattern shouldn't be installed at all.

@g7 Thanks for patch, but as it is just about media content and also yast packages should be installed per package and not as whole pattern, I would remove it also from opensuse medium ( so please update PR ).
And one more question I have is why SLE does not have PXE? I get few question and I have no clue. We should be able to easily add it same as for opensuse one.

Thanks for the review!

v2:

• As suggested, drop the pattern requirement everywhere, not only in SLES.
• Rebased on latest master

And one more question I have is why SLE does not have PXE? I get few question and I have no clue. We should be able to easily add it same as for opensuse one.

I've passed this question on, it's something that I would expect too to be honest, but let's see.

Thanks!
