servicemanager: remove performance hack 

See details in TODO.

This hack is either causing a bug or may be preventing us from solving
another bug. Until the more critical bug can be fixed, avoiding
early-boot reads of VINTF manifest files.

Bug: 151696835
Test: run, boot, check manifest logs that HAL services register
