FontAwesome: Fix remove_sign and ok_sign

[why]
The open variants of circle_xmark and circle_check are missing.

[how]
Rename the filled versions to their old (i.e. FA 4.2) names
(remove_sign and ok_sign) and let the open (regular) variants
find their place automatically.

Because we now have two more icons that would move all codepoints we can
either drop the icons that occupied the circle_xmark and circle_check
codepoints before, or we move the to the end (unpatched yet) region.

As these are just some more arrows, we drop them.

Dropped:
F30B F05C solid/right-long.svg
F30C F05D solid/up-long.svg

New:
F05C F05C regular/circle-xmark.svg
F05D F05D regular/circle-check.svg

Renamed:
RENAME circle_xmark to remove_sign (F057)
RENAME circle_check to ok_sign (F058)
