libqmi: fix patch for canonicalize_file_name() issue

The patch added in commit c78b65c4f1 was
bogus: it adds some code conditionally on HAVE_CANONICALIZE_FILE_NAME
being undefined, but there is nothing that defines
HAVE_CANONICALIZE_FILE_NAME if canonicalize_file_name() is already
provided by the C library.

This commit fixes that by adding the appropriate autoconf check.
