cmd/go: skip issue33139 when the 'cc' script command is unavailable

Browse Source 
With CGO disabled, the test suite tries to run the following and fail:

CGO_ENABLED=0 go test -run=TestScript/link_syso_issue33139 cmd/go
go test proxy running at GOPROXY=http://127.0.0.1:38829/mod
--- FAIL: TestScript (0.01s)

            # Test that we can use the external linker with a host syso file that is
            # embedded in a package, that is referenced by a Go assembly function.

            > [linux] [riscv64] skip
            > cc -c -o syso/objTestImpl.syso syso/src/objTestImpl.c
            FAIL: testdata/script/link_syso_issue33139.txt:15:
                unexpected error starting command:
                        fork/exec /dev/null: permission denied

CC was set to /dev/null (during build) in the scenario mentioned above

This patch replaces [!exec:cc] with [!cgo] because we care about the
availability of the 'cc' builtin and not the 'cc' executable in $PATH
