libctf: add missing header in BFD ELF check
Without this, GCC warns:
In file included from conftest.c:36:
../../libctf/../bfd/elf-bfd.h: In function 'bfd_section_is_ctf':
../../libctf/../bfd/elf-bfd.h:3089:10: warning: implicit declaration of function 'strncmp' [-Wimplicit-function-declaration]
3089 | return strncmp (name, ".ctf", 4) == 0 && (name[4] == 0 || name[4] == '.');
| ^~~~~~~
../../libctf/../bfd/elf-bfd.h:3089:33: warning: 'strncmp' argument 3 type is 'int' where 'long unsigned int' is expected in a call to built-in function declared without prototype [-Wbuiltin-declaration-mismatch]
3089 | return strncmp (name, ".ctf", 4) == 0 && (name[4] == 0 || name[4] == '.');
| ^
<built-in>: note: built-in 'strncmp' declared here
These warnings do not currently throw off the result of the configure
check, but it's better to squash them anyway.
