[OE-core] [PATCH 2/2] ptest.bbclass: add cleandirs flag to do_install_ptest_base

[Qi.Chen at windriver.com]

From: Chen Qi <Qi.Chen at windriver.com>

The do_install_ptest_base task should have cleandirs flag, just like
the do_install task. The ${D}${PTEST_PATH} directory should be cleaned,
Otherwise, there would be similar errors like below if the
do_install_ptest_base task is rerun.

    ln: failed to create symbolic link `xxx': File exists
