cmd/vet: honor analyzer flags when running vet outside $GOROOT/src

Additional vet flags specified by user are discarded if 'go vet'
is invoked outside $GOROOT/src to check a package under $GOROOT
(including those under "vendor" of $GOROOT), fix it by avoiding the
overwriting, the logic of detemining if the package under vetting
comes from $GOROOT remains untouched.

Also checked 'go tool vet <options> <cfg>' and 'go vet <options>
<user pkg>', both worked w./w.o this fix.

Fixes #35837.
