lib/extable.c: add missing prototypes
When building with W=1, a number of warnings are issued:
CC lib/extable.o
lib/extable.c:63:6: warning: no previous prototype for 'sort_extable' [-Wmissing-prototypes]
63 | void sort_extable(struct exception_table_entry *start,
| ^~~~~~~~~~~~
lib/extable.c:75:6: warning: no previous prototype for 'trim_init_extable' [-Wmissing-prototypes]
75 | void trim_init_extable(struct module *m)
| ^~~~~~~~~~~~~~~~~
lib/extable.c:115:1: warning: no previous prototype for 'search_extable' [-Wmissing-prototypes]
115 | search_extable(const struct exception_table_entry *base,
| ^~~~~~~~~~~~~~
Add the missing #include for the prototypes.
