Rather than having a hardcoded dependency on the build-directory layout,
use an explicit module-map environment variable, which rewrites requests
for modules and helper/libexec binaries to specific paths.
Pekka: This will help with migration to Meson where setting up the paths
according to autotools would be painful and unnecessary.
Emre: This should also help setting up the test suite after a
cross-compile.
Pekka: A caveat here is that this patch makes it slightly easier to load
external backends by abusing the module map. External backends are
specifically not supported in libweston.

v2:
Fixed ivi_layout-test-plugin.c:wet_module_init().
Do not change the lookup name of ivi-layout.ivi.
Improved documentation of weston_module_path_from_env() and made it cope
with map strings that a) do not end with a semicolon, and b) have
multiple consecutive semicolons.
Let WESTON_MODULE_MAP be printed into the test log so that it is easier
to run tests manually.
