scripts/sortextable: Rewrite error/success handling
The scripts/sortextable.c code has originally copied some code from
scripts/recordmount.c, which used the same setjmp/longjmp method to
manage control flow.
Meanwhile recordmcount has improved its error handling via:
3f1df12019f3 ("recordmcount: Rewrite error/success handling").
So rewrite this part of sortextable as well to get rid of the setjmp/longjmp
kludges, with additional refactoring, to make it more readable and
easier to extend.
No functional changes intended.
