Stop long fastfetch values from wrapping over the About logo (#6491)

Values longer than the remaining terminal width wrap back to column 0
and overwrite the logo column, which breaks the whole About layout. The
packages line triggers this on most systems.

Set display.disableLinewrap so overlong values clip at the right edge
instead. fastfetch documents this as the default but does not apply it
unless set explicitly.
