check-toolchain-clean.sh: fix shellcheck warnings

Fixes following complaints and suggestions:

 In scripts/check-toolchain-clean.sh line 2:
 eval `grep CONFIG_GCC_VERSION .config`
      ^-- SC2046 (warning): Quote this to prevent word splitting.
      ^-- SC2006 (style): Use $(...) notation instead of legacy backticks `...`.
