avocado: Fix BUILD_DIR if it's equal to SOURCE_DIR

I like to build QEMU from the root source directory [*], rather
than cd'ing into the build directory. This code may as well include
a search path for that, so that you can run avocado tests individually
without specifying "-p qemu_bin=build/qemu-system-arm" manually.

[*] See commit dedad02720 ("configure: add support for pseudo-"in source tree" builds")
