fix memory leak in get_task_name()

This series fixes some memory leaks related to the usage of the get_task_name() function from lib/fs.c.

Patch 2/2 addresses a coverity warning related to this memory leak, making the code a bit more readable by humans and coverity.

Changelog:
----------
v2 -> v3
- Use a better API for get_task_name(), passing to it a buffer and its lenght just like get_command_name().

v1 -> v2
- on Stephen's suggestion, drop asprintf() and use a local var for path; additionally drop %m from fscanf to not allocate memory, and resort to a param to return task name to the caller.
- patch 2/3 of the original series is no more needed.
