android: mm: Stub libhardware for build tests

Commit 66c618f378aa ("android: mm: generic: use
GRALLOC_HARDWARE_MODULE_ID") made libhardware a required dependency for
the Android camera HAL on non-Chrome OS platforms. This isn't an issue
for real devices, as Android provides libhardware, but it prevents
compile-testing the camera HAL on traditional Linux systems.

To restore the compile-test coverage, stub the libhardware function used
by the camera HAL when libhardware isn't found.
