Add StaticSharedLibsHostTests as PackageManager presubmit

ag/16128725 doesn't trigger CtsOsHostTestCases in the presubmit
process. However, StaticSharedLibsHostTests in CtsOsHostTestCases
verifies the Static Shared library functionalities of PackageManager.

Test: atest --collect-tests-only -p \
    frameworks/base/core/java/android/content/pm
Test: atest --collect-tests-only -p \
    cts/hostsidetests/os/test-apps/StaticSharedLibTestApp:presubmit
Test: atest \
    CtsOsHostTestCases:android.os.cts.StaticSharedLibsHostTests
