rtlil.cc: Fix #4427 
If a `RTLIL::Const` is composed of multiple strings, such as when using a ternary expression to select between two strings of different lengths, zero padding for the strings needs to be maintained.
Only leading (and trailing) null characters should be dropped from the decoded string, rather than all null characters.
