Now that we have referece to section name string table in
apply_relocate_add(), use it to

 - print the name of section being relocated
 - print symbol with NULL name (since it refers to a section)

before

| =========================================================
|	1c		0		7000e000  7000a07c 7000e000 []
|	40		0		7000a000  7000a0a0 7000a000 []

after

| Section to fixup .eh_frame @7000a060
| =========================================================
| r_off	r_add	st_value ADDRESS  VALUE
| =========================================================
|    1c	0	7000e000 7000a07c 7000e000 [.init.text]
