[PATCH v3 1/2] clip: copy password into all displays if possible

[Daniel Cordero]

pass only attempts to copy the password, first into wayland or otherwise
X, and it may still fail if the clipboard command isn't installed.

However, when using both wayland and Xwayland programs that need
password inputs, pass cannot know which clipboard it needs to place the
password.

Check the existance of the clipboard commands, and copy the password
into any that are available.
Move the shared code into a separate function that can be called by each
code path.

Only error if we couldn't attempt a copy into either clipboard.
