Fix a crash in jit.c
A user at Mozilla pointed out a crash in jit.c. In his situation, an
inferior using the JIT API exec'd an executable that did not use it.
This caused an assertion failure when jit.c:free_objfile_data called
delete_breakpoint with NULL.
This patch fixes the problem in the obvious way. New test case
included.
