scripts/sortextable: Handle relative entries, and other cleanups
x86 is now using relative rather than absolute addresses in its
exception table, so we add a sorter for these. If there are
relocations on the __ex_table section, they are redundant and probably
incorrect after the sort, so they are zeroed out leaving them valid
and consistent.
Also use the unaligned safe accessors from tools/{be,le}_byteshift.h
