[bug#44106] alacritty : add terminfo fix

[Fulbert <fulbert@bluewin.ch>]

  Hello Guix !

  When installed on an user extra-profile, `alacritty` does not add to
$TERMINFO_DIRS. Solved by using the attached patch. I have stolen this
fix from the guix `rxvt-unicode` package.

  Best regards,
  Fulbert
