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).
