fix: backward compatibility fix for tarball modules

[ykolbin]

#4593 affected backward compatibility, if someone try to install tarball module without tarball option.

Actually, it contains bad regular expression for following use cases:

1. Module name with digits (pm install pm2-module-name.tar.gz)
2. Modules/TAR.js can use Modularizer module_name as module_filepath, but fix for huntr #4593 regular expression is not allowed to specify full path to module (pm install full/path/to/module/pm2-module-name.tar.gz)
3. Modules/TAR.js can accept URL (pm install http://example.com/pm2/pm2-module-name.tar.gz)
