SetActionMap is now called with unsupposed flags from the tests and
skips some objects.

test_loadpaths_execute() was sometimes getting ERROR_ALREADY_EXISTS when
creating its temporary directoryi. That was probably because
GetTempFileNameW() only uses the low 16-bits of the 'random' LUID which
goes over a wider range, potentially leading to collisions in the lower
16-bits.
Avoid AllocateLocallyUniqueId() entirely and add a helper function to
create a guaranteed new directory.
Also try to use the current directory first as it is assumed to have
been configured to ward off anti-virus programs (specifically
Microsoft Defender) which is especially important when writing
executables to that location. Only switch to the system's temporary
directory if the current directory is not a writable location.

Today, RtlCreateActivationContext (CreateActCtxW) opens the source
manifest file via NtOpenFile without the FILE_SHARE_DELETE sharing mode.

This causes CreateActCtxW to fail if the source manifest file was
created with the FILE_DELETE_ON_CLOSE flag.  FILE_DELETE_ON_CLOSE is
often used for temporary files that should be automatically deleted
after use, even if the creator process crashes.

Fix this by specifying FILE_SHARE_DELETE for sharing mode when opening
the source manifest or module file.  This allows the source manifest or
module file to be marked as deleted while it is open.

Note that concurrent deletion is not an issue for the following reasons:

- The ability to read from an open file handle is unaffected by deletion
  of the corresponding file's name.

- RtlCreateActivationContext does not open the source manifest or module
  file by the given filename (lpSource) more than once.
