Subject: [PATCH] Fix path for errno.h

Fix warnings when built with musl libc by using the correct path for
errno.h as defined in POSIX.

Fixes the following warning:
In file included from /home/ncopa/src/exiv2/src/http.cpp:74:
/usr/include/sys/errno.h:1:2: warning: #warning redirecting incorrect #include <sys/errno.h> to <errno.h> [-Wcpp]
