[PATCH 1/1] tinfoil.py: Check if BUILDDIR exists

[Amanda Brindle]

Check if BUILDDIR exists in order to deterimine if a tinfoil using
script is running without having called oe-init-build-env (or similar).
If not, instruct user to initialise the build environment, and then
error out immediately. Before, tinfoil would hang for 30s before
erroring out.

Fixes [YOCTO #12096]

We should be raising an exception here - tinfoil is utility code, it shouldn't 
be calling sys.exit(). Additionally, bitbake shouldn't be referring to 
oe-init-build-env, that's something from OpenEmbedded; even mentioning Tinfoil 
isn't going to be much use to the user. I would simply raise a custom 
exception class with the message "Build environment not initialised" or 
similar, and if tinfoil-using want to catch that exception and produce a more 
friendly message they can fairly easily do so.

Cheers,
Paul

This was also triggering on the autobuilder tests so something isn't
quite right here:
