[PATCH 3/4] binman: Have faked binaries live in the output directory.

[Tom Rini <trini@konsulko.com>]

In general, and for Azure specifically, we need to have files created in
the output directory and cannot assume a writable source directory.
Rework the faked blob support to put the faked binary in to the output
directory and then stop the test from deleting the now non-existent
file.
