Fix Microdroid Benchmark tests

Commit 7bc146c6659d5ea35a8219f5abea1f50950f4417 switched from using
config file vm_config.json to directly specifying the binary as
MicrodroidTestNativeLib.so. But the benchmarks use a different APK
from the tests, and here the binary is actually called
MicrodroidIdleNativeLib.so.

Bug: 255298237
Test: atest MicrodroidBenchmarkApp
