Fix a few minor symbol library inheritance bugs. 

Don't clobber value file when load aliases in legacy symbol library cache
parser.

Use actual symbol library LIB_PART pointer rather than a flattened copy
of the symbol.  This fixed a bug when displaying the parent field in the
message panel for derived symbols.

Simplify the flatten code by copying the parent and updating the lesser
information from the inherited symbol.
