[PATCH] tests: Let xorriso fixely assume UTF-8 as local character set

[Thomas Schmitt]

iso9660_test fails if the effective locale is not UTF-8. This happens
because xorriso needs to convert file names and FSLABEL to UCS-2 when
preparing a Joliet tree. grub-fs-tester obviously intends to use UTF-8
as character set, but xorriso assumes by default the result of
nl_langinfo(3) with item CODESET.
So override the result of nl_langinfo(CODESET) by options of xorriso -as
mkisofs.
