icu: fix build breakage

Commit 2de88f9d9c07f7e693449f94858d96053222acea / issue 21833
changes UChar_t* to char16_t* in ures.h (lines 815, 840, 862, 885
at least, functions ures_getUnicodeString() and friends).

This breaks compilation of code using -DUCHAR_TYPE=uint16_t.

Workaround: revert to previous version, like Gentoo does
