[OE-core] [PATCH V2 3/8] oeqa/sdkext/devtool.py: remove sources before run test cases

[Robert Yang]

Fixed:
MACHINE = "qemux86-64"
require conf/multilib.conf
MULTILIBS = "multilib:lib32"
DEFAULTTUNE_virtclass-multilib-lib32 = "x86"

$ bitbake core-image-minimal -cpopulate_sdk_ext
[snip]
ERROR: Source tree path /path/to/tmp/work/qemux86_64-poky-linux/core-image-minimal/1.0-r0/testsdkext/tc/workspace/sources/v4l2loopback-driver already exists and is not empty\n'
[snip]

This is because the test case will run twice
(environment-setup-core2-64-poky-linux and
environment-setup-x86-pokymllib32-linux), it would fail in the second
run, 'devtool reset' can not remove sources, so remove it before running
test cases.
