Eddie Lebow 1997a8f7e2 ShellDetect: fall back to filetype if no hashbang
Some files lack a hashbang line but still have an unambiguous filetype.
For example, the file `.zshrc` has the filetype `zsh`.

Augment ale#handlers#sh#GetShellType to fall back to the filetype if
no hashbang line can be found.
