FDO: do not support host modules

Summary:
If built with BUILD_FDO_INSTRUMENT alone, host modules will fail at runtime (during build)
due to failing to create /data in most standard unix user permission cases. If the user does
have full permission to /, /data/profile/ will be created and profiles will be generated there.
Any file generation in the Android Build System should be kept to $OUT.

This commit fixes this bug.

Test Plan:
Build with BUILD_FDO_INSTRUMENT without additional configuration, and host modules will no longer generate profiles
at their runtime.
