[Skiboot] [PATCH] boot-tests: allow running boot_test.sh via a symlink

[Andrew Donnellan]

In boot_test.sh, use readlink when working out the path to source
{fsp,bmc}_support.sh, so the script doesn't fail when run using a symlink
from outside the boot-tests directory.

Briefly tested, seems to work. readlink is in coreutils and busybox.
