Revert^2 "Build libgptutils with Android.bp.""

This reverts commit 215189f0b9ff44d28c2b4ace0abb26854b201271.

The previous landing broke checkbuild targets due to namespace issue. As
libgptutils.msm8998 was exposed to global namespace (previously guarded
via conditionals in Android.mk), but had a missing dependency on
nonexposed msm8998 kernel headers.

The relanding adds a Soong namespace of hardware/qcom/msm8998, to ensure
modules only getting built as needed.

Bug: 34254109
Test: Sideload on taimen.
Test: `m -j checkbuild` with aosp_x86-eng
