[OE-core] [meta][PATCH 1/3] go-vendor.bbclass: Fix test file exclusion and license propagation

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

Two bugs in do_go_vendor:

1. The shutil.ignore_patterns glob was "*._test.go" (with an extra dot),
   which never matches standard Go test files (*_test.go). Remove the
   extra dot.

2. The license-propagation block used os.path.join(src, "LICENSE") as the
   copy destination, writing into the already-processed vendor.fetch source
   tree rather than into the vendor destination directory.  Switch to
   os.path.join(dst, "LICENSE") so the LICENSE lands in vendor/ where go
   tools and licence scanners expect it.  Also fix the guard condition from
   not os.path.exists(subdir) (checking an unrelated relative name) to
   not os.path.exists(subdirLicense) (checking the actual target).
