[PATCH, go testsuite]: Fix PR48501, 64bit-out.go, select5-out.go, tmp.go compilation times out

[Uros Bizjak]

Hello!

Attached patch introduces adjustable timeout value to go testsuite. I
have added the fix for select5-out.go compilation timeout error, since
this test fails on my target. Following this example, it is trivial to
fix other timeout issues in go-test.exp.

        PR go/48501
        * lib/go.exp (go_target_compile): Append timeout= to options.
        * go.test/go-test.exp (go-gc-tests): Add dg-timeout-factor for
        select5-out.go test on alpha*-*-* targets.

Tested on alphaev8-pc-linux-gnu.

OK for mainline?

Uros.
