fix(modules): strip inline comments in modules.list parser

3bcf2e1 added nft_numgen / nft_hash / nft_limit / nft_log to both module
lists but in a format the inject parser doesn't handle:

  nft_numgen     # numgen random/inc mod N vmap — Service endpoint LB

The parser's only comment skip is `case "$mod" in \#*|"") continue ;;`
which matches lines STARTING with #, not lines with inline #-comments.
So each new line was passed to modprobe verbatim as a single (invalid)
module name, modprobe returned nonzero, and the .ko never made it into
the initramfs. ls'ing the rootfs after the rootfs rebuild confirmed:

  ls .../lib/modules/*/kernel/net/netfilter/ | grep nft_numgen
  <empty>

Two changes:

1. Strip inline comments from the new entries in modules.list and
   modules-arm64.list. Each module name on its own line, matching the
   convention the rest of the file uses.

2. Harden the parser in inject-kubesolo.sh to handle "name # comment"
   regardless. Single-line tweak: `mod="${mod%%#*}"` before the
   continue check. Prevents a future contributor's inline doc from
   silently dropping a module the same way.

After rebuilding the rootfs on the Odroid (no kernel rebuild needed —
this is a rootfs-only change), the four .ko files should appear at
build/rootfs-work/rootfs/lib/modules/*/kernel/net/netfilter/.
