Added support for white-spaces in target

[DobroAlex]

It might have something to do with the fact that I run on WSL2 (or me being stupid). However, if the target directory for searching contains whitespace (no matter if they are escaped using "/some path/dir" or /some \path/dir" it causes errors.

Examples:

• Without this patch:

  • Sample 1
    Input:
    /c/Users/User/source/php-malware-finder/php-malware-finder/phpmalwarefinder -c "/c/Users/User/source/php-malware-finder/php-malware-finder/php.yar" -t 4 ~/white\ space\ test/php_malware_finder/test_1/
    Output:
    error: could not open file: /home/alex/white
  • Sample 2
    Input:
    /c/Users/User/source/php-malware-finder/php-malware-finder/phpmalwarefinder -c "/c/Users/User/source/php-malware-finder/php-malware-finder/php.yar" -t 4 "white space test/php_malware_finder/test_1"
    Output:
    error: could not open file: white

• With this patch:

  • Sample 1

    Output (as expected):
