Revert "Implement Manager/ServiceRootUptime"

This reverts commit ee61a619da7f180a3148317d569d2dabd1cd9832.

This feature was tested against an old version of schemas, and upstream
DMTF seems to have changed the definition in the meantime.  This wasn't
caught because of the same test failure as yesterday.

Mea Culpa
