patch: fix musl compile without TLS

[Lucian Cristian]

if DUSE_TLS is not specified and libc is musl the compile will fail with:

posttls-finger.c: In function 'usage':
posttls-finger.c:1607:5: warning: implicit declaration of function 'fprintf' [-Wimplicit-function-declaration]
fprintf(stderr, "usage: %s [-acStTv] [-h host_lookup] [-o name=value] destination\n",
^
posttls-finger.c:1607:5: warning: incompatible implicit declaration of built-in function 'fprintf'
posttls-finger.c:1607:5: note: include '<stdio.h>' or provide a declaration of 'fprintf'
posttls-finger.c:1607:13: error: 'stderr' undeclared (first use in this function)
fprintf(stderr, "usage: %s [-acStTv] [-h host_lookup] [-o name=value] destination\n",
^
posttls-finger.c:1607:13: note: each undeclared identifier is reported only once for each function it appears in
Makefile:63: recipe for target 'posttls-finger.o' failed

https://github.com/openwrt/packages/pull/4093#issuecomment-283521423

if TLS defined, stdio.h related problems will not appear.
Because the openssh related header file contains "#include <stdio.h>" line.

Patch follows:
