ICU-20363 Out of boundary write on empty file.

If gencnval encounters an empty input file the function resolveAlias
triggers an out of boundary write due to uniqueAliasArr pointing to
a 0 byte reserved memory address.

This patch protects the code in question with a check for
knownAliasesCount being not 0.
