package/lua-utf8: remove upstream patch

Running the following command when the package is selected:

    make lua-utf8-patch

fails with error message:

    Applying 0001-Explicitly-include-limits.h-instead-of-transitively-.patch using patch:
    can't find file to patch at input line 48

The package patch has been introduced in commit [1], while Buildroot
was in RC cycle. This patch was useful against version 0.1.5. The
package version was bumped to version 0.1.6 in commit [2] in the
branch next, which includes this patch.
