Fix shell function symlink_contents_to_dir, add test
- test for the case when we symlink the contents of two directories with the same inner directories (include)
- the test data of the test for shell script helper also changes, as it uses the real shell toolchain implementation text
- Fixes the issue from #330
Fix shell_script_helper.bzl to replace function calls inside function texts.
Add test for shell_script_helper.bzl.
In particular, this fixes the case when some of the shell toolchain functions calls other shell toolchain functions (symlink_contents_to_dir and symlink_to_dir).
