That way, lit's builtin 'env' command can be used for the 'env' bit.
Also it's clearer that way that the 'not' shouldn't cover 'env'
failures.

'ignore-non-existent-contents' stopped working after r342232 in a way
that the actual attribute value isn't used and it works as if it is
always `true`.
Common use case for VFS iteration is iterating through files in umbrella
directories for modules. Ability to detect if some VFS entries point to
non-existing files is nice but non-critical. Instead of adding back
support for `'ignore-non-existent-contents': false` I am removing the
attribute, because such scenario isn't used widely enough and stricter
checks don't provide enough value to justify the maintenance.

These tests do not appear to be Darwin-specific, and this REQUIRES: appears to
be hiding a real bug; this change is just restoring the prior state to get the
buildbots happy again while we investigate. (The system-darwin requirement is
covered by PR32851.)

Also remove the apparently-unneeded REQUIRES (the tests also pass on at least
Linux, and don't appear to have anything Darwin-specific in them).

The most common workflow with module reproducers involves deleting the
module cache before running the script. This happens because leftovers
from the crash are present in the cache and could trigger unrelated and
confusing errors, misleading from the initial reproduction intent.
Change this to point to a clean path but leave the leftovers untouched.

When -fmodules is on, the reproducer invocation currently leave paths
for include-like flags as is. If the path is relative, the reproducer
doesn't know how to access that file during reproduction time because
the VFS cannot reason about relative paths.
Expand relative paths to absolute ones when creating the reproducer
command line. This allows, for example, the reproducer to work for
crashes while building clang with modules; this wasn't possible before
because building clang requires using relative inc dir from within the
build directory.
