build: fix cctest target --with-dtrace

Currently the cctest target will fail on linux when configured
--with-dtrace:

/node-v9.2.0/out/Release/obj.target/node/src/node_dtrace.o:
In function `node::DTRACE_NET_SERVER_CONNECTION(
    v8::FunctionCallbackInfo<v8::Value> const&)':
node_dtrace.cc:(.text+0x103): undefined reference to
`node_net__server__connection_semaphore'
/node-v9.2.0/out/Release/obj.target/node/src/node_dtrace.o:
In function `node::DTRACE_NET_STREAM_END(
    v8::FunctionCallbackInfo<v8::Value> const&)':
...

This is because node_dtrace_provider.o is not linked by the cctest
target.

This commit tries to fix and simplify the conditions in cctest target
so that node_dtrace.o is included for all operating systems that support
dtrace, include node_dtrace_ustack.o for all operating systems except
mac and linux, and include node_dtrace_provider.o for all operating
systems except mac.
