[SSE-C]: avoid encrypting empty objects. (#5525)

Browse Source 
This change adds an object size check such that the server does not
encrypt empty objects (typically folders) for SSE-C. The server still
returns SSE-C headers but the object is not encrypted since there is no
point to encrypt such objects.

Fixes #5493
