Subject: [PATCH] vmm: fix --net fd helptext for list syntax

The --net help text documented fd as fd=<fd1,fd2...>, but
comma-separated FD lists in option values must be bracketed to avoid
top-level option splitting.

Update NetConfig::SYNTAX to use fd=<[fd1,fd2,...]>, matching parser
behavior and existing net parsing tests:
`cargo test -p vmm test_net_parsing`
