go get -t does not work due to wrong import in test

[targodan]

go get -t github.com/0xrawsec/golang-win32 fails with "package win32: unrecognized import path "win32": import path does not begin with hostname"

The import in win32/dbghelp/test/dbghelp_test.go should use the full import path as defined in go.mod, i.e. import "github.com/0xrawsec/golang-win32/win32" as opposed to just import "win32"
