oeqa/selftest/wic: fix PATH for wic.Wic2.test_extra_partition_plugin

Without importing PATH from the wic-tools recipes, the build host PATH
is used and this test may fail depending on tools (parted, dumpe2fs,
...) availability. This triggers build faillure on AB (e.g. [0])

To fix this, import PATH from wic-tools and ensure the original
environment is restored after.

Since this indent a block of code into a try/finally block, here is the
diff ignoring white spaces change:
