Subject: [PATCH] getopt: fix strncmp() declaration

The strncmp() declaration does not conform with the standard as to the
type of the 'n' parameter. Fix this to avoid the following build failure
with musl libc:

n file included from main.c:61:0:
getopt.c:175:13: error: conflicting types for 'strncmp'
 extern int  strncmp(const char *s1, const char *s2, unsigned int n);
             ^~~~~~~
In file included from main.c:49:0:
.../host/x86_64-buildroot-linux-musl/sysroot/usr/include/string.h:38:5: note: previous declaration of 'strncmp' was here
 int strncmp (const char *, const char *, size_t);
     ^~~~~~~
