Devirtualize ScriptParserBase. NFC.

ScriptParserBase class is a container of collection of various methods
to parse linker script-ish text. It had a virtual method `run` to run
the parser. But we don't have to enforce its descendents to implement
that. It's up to them.

This patch removes pure virtual function `run`.
