Shell (Linux): don't detect hyfetch as shell on NixOS (#1149)

On NixOS, Hyfetch has been placed in a "wrapper script" in order to set the correct PATH that it needs to run correctly.
As a result, the actual Hyfetch executable has been renamed `.hyfetch-wrapped`, which results in this check failing to detect Hyfetch on NixOS properly.

With this patch the logic has been changed to check if the program name contains the string `hyfetch`, which should work for the NixOS case.
