This seems to speed things up in cmake by 10% or so, which is consistent
with expectations (using `ccache` adds 15-30ms in experimental testing;
cmake checks are often faster than that).

CCACHE_BASEDIR used to be set to sysroot so that ccache can reuse
compilation results across different boards. This is not useful
on builders and also less useful for board builds since we set
closer to target CFLAGS now.
It also breaks use of -fmacro-prefix-map option in clang/gcc.
So rip it out and simplify the rest of code.

Previously, we only supported setting env variables
to empty, but not to remove it. This lead to the case
that we never removed the CCACHE_DISABLE env variable,
which kept the ccache disabled, and caused a performance
regression compared to the old wrapper as the new wrapper
didn't use the ccache in this case.
This cl also adds tests for the real exec and run commands
to prevent regressions in these cases.

commands, error messages and exit codes.
Also:
- implements the -Xclang-path= flag as use case of calling
a nested command.
- adds tests for forwarding errors, comparing against the
old wrapper, and exit codes.
- captures the source locations of errors in error messages.
- compares exit codes of new wrapper and old wrapper.
