[meta][PATCH v2 3/3] go-vendor.bbclass: Run vendor_unlink task under fakeroot

[John Ripple <john.ripple@keysight.com>]

do_install and do_package both run under fakeroot (pseudo), which keeps
pseudo's ownership/inode database in sync with what is actually on disk
under D. do_vendor_unlink runs between them but was never marked
fakeroot, so its os.unlink() of the vendor symlink happened outside of
pseudo's view: the file disappeared from disk but pseudo's database
still held a stale record for that path/inode.

The next fakeroot task to touch that path (do_package) then finds the
on-disk state and pseudo's database disagreeing, and pseudo aborts with
"path mismatch" / "inode mismatch" errors, failing do_package.

Mark do_vendor_unlink fakeroot, matching do_install and do_package, so
its filesystem operations are tracked by pseudo consistently.
