Fix rofi-gopass to use correct user field

gopass, by default creates a field called `username` to contain the
corresponding login name. rofi-gopass was looking for a field called
`user`, and ignored username which lead to it only inputting the
password for any site where gopass created the login credentials.

This is now fixed, all that remains is to revert the manually changed
fields back to `username`.
