Since 'out' is defined as a keyword in scanner.l, using it as a chain
priority name without quotes is not possible. Fix this by introducing
'extended_prio_name' in bison which may be either a string (as before)
or OUT, which is then converted into a string.
Fixes: c8a0e8c90e2d1 ("src: Set/print standard chain prios with textual names")
