The hal-api library are used by the various process.
In order to support the easy debugging, show the process name
who get/put the hal-api library.

Example log with process name,
HAL_MODULE_TBM: Get HAL backend: name(vc4)/vendor(Samsung)/library(/hal/lib64/libhal-backend-tbm.so)/count(1) by /usr/bin/enlightenment
HAL_MODULE_TBM: Get HAL backend: name(vc4)/vendor(Samsung)/library(/hal/lib64/libhal-backend-tbm.so)/count(1) by /usr/bin/boot-animation
