Musl libc compat for canonicalize_file_name()

Musl libc compat for canonicalize_file_name()

while building libqmi 1.18.0 I noticed warnings from gcc to include <stdio.h> in src/libqmi-glib/qmi-utils.h

this is a revised patch with the extra include for musl libc

The suggested patch creates an issue with packages like modem-manager since the header is used as a interface definition to the libqmi library.  Instead, suggesting the new attached patch.

patch including static func in impl instead of as a inline in header

It's just used once, so why not just...

         tmp = g_strdup_printf ("/sys/class/%s/%s/device/driver", subsystems[i], device_basename);

#if defined HAVE_CANONICALIZE_FILE_NAME
         path = canonicalize_file_name (tmp);
#else
         path = realpath (tmp, NULL);
#endif
         g_free (tmp);

For reference, that's basically what I had in this patch I carry for the openwrt libqmi builds:

Just defaulted it to use realpath() instead of adding more complexity. None of the realpath() limitations really affect us.
