RFR(S): 8241638: launcher time metrics alway report 1 on Linux when _JAVA_LAUNCHER_DEBUG set(Internet mail)

[Henry Jen]

Internal test shows that inline implementation is not working for some Solaris artifacts, because the -DHAVE_GETHRTIME is not consistently defined, so it is actually broken. :)

I verified that either move implementation into .c as a function body[1] or change to #ifdef __solaris__[2] will fix that. So I think we will change to detect __solaris__ as webrev[2] rather than have an extra #define. If some other build want to have that, they can be modify that #ifdef easily.

As I look into it, I found Mac have similar implementation with minor mistake, so I fixed that as well. Please review following based on zhanglin’s patch.

I’ll push [2] once I got a +1.
