[Toybox] Extend seq to support -f (format string) and -s (separator) as requested by LSB

[Elie De Brauwer]

Hello all,

In attachment you can find a patch (including tests) which extends seq 
to support -f (format string) and -s (separator) commandline options, 
these changes are stated in the LSB documentation of seq.

Demo-time:
edb at lapedb:~/edb-stuff/toybox/toybox$ ./toybox seq -f'%+03g' -s '<=' -10 
5 10
-10<=-05<=+00<=+05<=+10
