fix(genesis): only wait 20s for NIC init on ppc64

Browse Source 
The genesis boot script sleeps 20 seconds unconditionally with the comment
"wait for NIC initialization", but that wait exists solely for System P LE
(ppc64) hardware discovery -- the surrounding section is explicitly ppc64
only. Every x86_64 and aarch64 node therefore pays a needless 20s delay on
each genesis boot.

Move the sleep inside the `[[ ${ARCH} =~ ppc64 ]]` block so only ppc64 waits.
Applied to the base script and both dracut_105 (el, ubuntu) variants.

Recovered from the unmerged lenovobuild branch (original d0916d9d).
