Allow adding executables to exclusions

[ameshkov]

Issue Details

Right now, there’s no way to add an executable to the exclusions.

• Starting to add an exclusion
• Press Cmd+Shift+. to show all directories
• Go to add /usr/bin/curl
• But it simply doesn’t let me select it

Proposed solution

• Allow selecting any executable
• Use the default macOS executable icon for it
• In the popover show the full path to the executable (for app bundles you still need to only show path to the .app folder).

Alternative solution
