Ensure that unwanted tests are correctly excluded when various build
tags are specified, i.e. when the code that they test would be excluded
from compilation.

The textfile collector will now provide a unified metric description
(that will look like "Metric read from file/a.prom, file/b.prom")
for metrics collected accross several text-files that don't already
have a description.
Also change the error handling in the textfile collector tests to
ContinueOnError to better mirror the real-life use-case.

* collector: Unwrap glob textfile directories
* collector: Store full path in mtime's file label
The point is to avoid duplicated gauges from files with the same name in
different directories.
This introduces support for exporting from multiple directories matching
given pattern (e.g. `/home/*/metrics/`).
