rS357591: Read the breakpoint instruction to determine its length in BKPT_SKIP.

Summary

This fixes continuing from debug.kdb.enter=1 after enabling the use
of compressed instructions since the compiler can emit the two byte
c.ebreak instead of the 4 byte ebreak.

Test Plan

sysctl debug.kdb.enter and then 'c' to continue
