oe/path.py: fix for "Argument list too long"
Issue: LIN9-1648
Fixed when len(TMPDIR) = 410:
$ bitbake core-image-sato-sdk
[snip]
Subprocess output:
/bin/sh: /bin/cp: Argument list too long
ERROR: core-image-sato-sdk-1.0-r0 do_rootfs: Function failed: do_rootfs
[snip]
This is because "copyhardlinktree(src, dst)" does "cp -afl src/* dst",
while src/* is expanded to "src/file1 src/file2, src/file3..." which
causes the "Argument list too long", use ./* as src and change cwd in
subprocess.check_output() to fix the problem.
