sci-libs/cantera: 2.4.0-r1. Disable default optimization flag "-O3"

By default the optimization flag "-O3" was used with warning "-Wno-inline".
The addition of expicit build option optimize_flags="-Wno-inline"
now disables default "-O3" optimization flag in favor of options
taken from "make.conf".
