[yocto] [ptest-runner] ptest-runner: make DEFAULT_DIRECTORY be able to be defined when compiling

[Li Zhou]

In yocto project ptest data are installed to
PTEST_PATH ?= "${libdir}/${BPN}/ptest". Here make DEFAULT_DIRECTORY
be able to be defined outside of c code (e.g. passed in by CFLAGS),
in case libdir isn't "/usr/lib", which will cause "No ptests found"
error when running "ptest-runner" command. We will pass libdir to
DEFAULT_DIRECTORY when compiling to avoid that error.
