fix: genesis dep groups should supports relative file path

[quake]

What problem does this PR solve?

When running ckb dev chain locally, user may put some custom scripts into the genesis block for development convenience, however, currently only system_cells supports relative paths, while dep_groups does not.

works:

[[genesis.system_cells]]
file = { file = "../compiled_binary/always_failure" }
create_type_id = true
capacity = 100_000_0000_0000

not working:

[[genesis.dep_groups]]
name = "always"
files = [
  { file = "../compiled_binary/always_success" },
  { file = "../compiled_binary/always_failure" },
]

this PR resolved this issue.
