Support running tests from different build directories

Browse source 
The tests that run exec-fd-leak-checker expect the binary to be located
in the current directory. This is not always the case; for instance, the
binaries could be built under `tests`, but be invoked under the
top-level build directory.

We can use an environment variable to control what's the location of the
test binaries, and fall back to the current directory if the variable is
unset.
