Remove path_length config option
I've misunderstood the FS limits, 255 is for filename, not path.
Path is limited only by libc, it's 4096.
The default outtmpl in musicdlp contains slashes, so it's a path.
But YDL considers it to be a filename, so the whole
outtmpl formatting result is trimmed to path_length.
Do we really need this? I think there are no "malicious" long-named tracks :)
