[Buildroot] [PATCH v1] atftp: fix musl compile

[Peter Seiderer]

- add missing __THROW, __BEGIN_DECLS, __END_DECLS and __attribute_pure__
  defines in atftp own argz.h file

- add missing sys/types.h include in tftp.h and tftpd.h

Fixes [1]:

argz.h:61:1: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'extern'
 extern error_t __argz_create (char *__const __argv[], char **__restrict __argz,
 ^
argz.h: In function 'argz_create':
argz.h:64:34: error: expected declaration specifiers before '__THROW'
        size_t *__restrict __len) __THROW;
