Wez Furlong 9cd72fefe2 pty: cmdbuilder: check for executable access when resolving program ... `wezterm start -- /etc/profile` would crash on macOS because `/etc/profile` isn't executable. This commit checks for executable access as a prereq for both the path search and the absolute path cases and generates a non-crashing error: ``` $ wezterm start -- /etc/profile 17:24:03.574 ERROR wezterm_gui > Unable to spawn /etc/profile because it doesn't exist on the filesystem or is not executable (EACCES: Permission denied); terminating ```		2022-08-09 17:29:22 -07:00
