[OE-core] [PATCH] oeqa/selftest/recipetool: Fix appendfile_binary test on opensuse131

[Richard Purdie]

On OpenSUSE 13.1, /bin/ls is a symlink to /usr/bin/ls. This means the
test doesn't use a binary file an fails on that system.

Ensure we resolve any symlink using readlink to avoid this failure.
