cc: Remove unneeded ubsan library linkage on host
The sanitizer runtime logic was rewritten in aosp/2438959 to simplify
static sanitizer library selection. However, enabling ubsan diagnostics
for host tests would result in incorrectly adding an unnecessary
libclang_rt.asan.so dependency.
This check should have been removed as well -- the library dep
determination for c.sanitize.Properties.UbsanRuntimeDep is now handled
higher up in the logic.
(Some formatting fixes are included as well)
Bug: 323237381
Test: UBSanitized Host test with diagnostics runs correctly.
