Add option to by bypass find filtering

[rsanzante]

The script checks every file and folder using find (

drupal-fix-permissions-script/drupal_fix_permissions.sh

Line 166 in 3bb7845

find "$1" $detected_vendor_path \( ! -user $drupal_user -o ! -group $httpd_group \) \( -type f -o -type d \) -print0 | xargs -r -0 -L20 chown $drupal_user:$httpd_group

).

This could be non-performant if all files and folders or most of them need fix.

A script flag/option can be added to skip this filtering.

Next steps

• Test that there's really a performance penalty and measure it
• Add the option if the penalty is big enough
