symbols: remove redundant mappings and assignments for <LVL3> and <LVL5>

In symbols/pc, <LVL3> gets ISO_Level3_Shift assigned and mapped to Mod5,
and <LVL5> gets ISO_Level5_Shift assigned and mapped to Mod3, and there
is not any layout nor any option that changes anything in this.  Thus,
repeating these assignments and mappings is entirely superfluous.
