[Bug] Ignoring files in .ocplint does not work when ocp-lint is run in a sub-directory

[david-maison]

Let's take the following example:

$ tree -a
.
├── dir
│   ├── bar.ml
│   └── bar.mli
├── foo.ml
├── foo.mli
└── .ocplint

1 directory, 5 files

$ cat .ocplint
plugin_parsing = {
  get_features = {
    enabled = false
  }
}

plugin_parsetree = {
  pattern_guard = {
    ignore = [ "dir/bar.ml" ]
  }
}

We do not use the db in this case.

Then, we run:

$ ocp-lint
Scanning files in project "."...
Found '6' file(s)
Running analyses... 6 / 6
Mergin database...
== New Warnings ==
  * 0 file(s) were linted
  * 0 warning(s) were emitted:
  * 0 file(s) couldn't be linted

And then:

$ cd dir && ocp-lint
Scanning files in project "."...
Found '2' file(s)
Running analyses... 2 / 2
Mergin database...
== New Warnings ==
  * 1 file(s) were linted
  * 1 warning(s) were emitted:
      * 1 warning(s) raised by "plugin_parsetree"/"pattern_guard.1"/warning #1
  * 0 file(s) couldn't be linted

The configuration file is successfully read (because we do not have the "get_features" warnings), but I expected the file "bar.ml" to be ignored for the rule "pattern_guard". Is it normal?
