Fix libicu.so missing in general-tests.zip

The libs under host/testcases/art_common/out/host/linux-x86/lib64/
in general-tests are generated by the art_common module in
Android.gtest.mk.

On host, the correct lib name is not libicu-host.so, but libicu.so, because
unique_host_name is false in the libicu Soong module. This CL corrects
the .so name in the art_common module.

Bug: 160350521
Test: Verified the libicu.so exists in general-tests.zip
