Disable the test "Test against HP-UX 11.11 bug: No converter from EUC-JP
to UTF-8 is provided" since we don't support HP-UX and if the euc-jp is
not installed on the host, the dependence will be built without iconv
support and will cause guild-native building fail.
The patch is similar as 0470bd7a9658d3[libunistring: remove the test to
convert euc-jp in configure]
