sci-biology/mira: Force rebuild of lexer C++ source files

Upstream ships pregenerated C++ source files for its lexers.  These
files fail to compile under newer versions of GCC.  This update forces
them to be rebuilt by removing them before compilaiton starts.

Package-Manager: Portage-2.3.3, Repoman-2.3.1
