[OE-core] [PATCH] oe-selftest: devtool: Support meta being a symbolic link

[Peter Kjellerstedt]

oe-selftest's devtool tests have been broken since commit 2457cd57
(oe-selftest: devtool: avoid parallel races by using temporary copy of
core) if meta is a symbolic link.

I have tested this change with OE-Core, Poky and our own setup (where
meta is a symbolic link).
