The diag command crashes if a hook script is a broken symlink

[pbeckingham]

The diag command tries to determine execute permission on a broken symlink and this crashes. This may require a libshared/src/FS.cpp change, or at a minimum just the diag command.

Reproduce with:

$ cd ~/.task/hooks/
$ ln -s /missing on-add.missing
$ task diag

When I try to reproduce this issue in the fashion how @pbeckingham describes it, the task diag command does not crash. It rather reports:

Inactive: on-add.missing        (not executable) (symlink)

(Running task 2.5.1)

Also on the current taskwarrior release task 3.1.0 is is no longer crashing.

Therefore, I would close this issue as its not reproducible at the moment or working.
