fix: multiple minor fixes (#29)

* fix: set SETVARS_COMPLETED after installing/activating Intel toolchain, don't unset local variable in install_intel_apt bash function, test intel and intel-classic on ubuntu-20.04

* include SETVARS_COMPLETED in export_intel_vars, add explanatory comment in install_intel_win"

* set CXX on intel/windows, cleanup

* ifx 2021.3 install fails on ubuntu
