community/linux-postmarketos-qcom-sm6350: adjust config (MR 3416)

Switch to minimal config that I've been using for development for the
last months, with some minor modifications. In addition to that enable
all the kconfig options that will be a part of the new
pmb:kconfigcheck-community (anbox/waydroid + iwd + nftables + containers
+ zram + netboot).

Note by ollieparanoid:
Re-applied it after I just reverted it. Now realized that I didn't need
to revert this in the first place, this is and aarch64 package and the
cross compilers (x86_64 packages) needed to be published. Anyway, the
gcc mess is mostly resolved now, see issue 2167.
