g_format_size_for_displayl() is deprecated since 2.30

I met a following warning even if ruby-glib2 (GLib Ruby binding) defines the macro like below[1]:

#define GLIB_VERSION_MIN_REQUIRED GLIB_VERSION_2_28


rbglib_fileutils.c: In function ‘rbglib_m_format_size_for_display’:
rbglib_fileutils.c:56:5: warning: ‘g_format_size_for_display’ is deprecated: Use 'g_format_size' instead [-Wdeprecated-declaration ns]
     return CSTR2RVAL_FREE(g_format_size_for_display(NUM2OFFT(size)));

        ^~~~~~~~~~~~~~~~~~~~~~~~~

I think GLib must use GLIB_DEPRECATED_IN_2_30_FOR instead of GLIB_DEPRECATED_FOR like the attached patch.
Because g_format_size_for_display() has been deprecated since version 2.30[2].

I can suppress the warning with attached patch.
