i3-sensible-pager: sanitize LESS environment variable (#5111)

When an error is encountered such as "The configured command for this shortcut
could not be run successfully", the "show errors" button on i3-nagbar doesn't
work if $PAGER is less, and $LESS contains either the -E or -F flag (the
window pops up, but immediately disappears).

Strip these flags from the LESS environment variable before invoking $pager.

# Hopefully one of these is installed (no flamewars about preference please!):
# We don't use 'more' because it will exit if the file is too short.
# Worst case scenario we'll open the file in your editor.
