Stefan Agner f86fcbd609 Fix shellcheck issues (#1341)
* Fix issue with latest shellcheck version

The latest shellcheck versions use a new error number for non-POSIX
string replacement. Change to ignore this new error number.

* Ignore shellcheck issue about not following sourced files

Newer shellcheck versions also warn when shellcheck does not follow
sourcing of files with known path:
  Not following: ./meta was not specified as input (see shellcheck -x).

We check those files separately so ignore this error for the two scripts
affected.
