RFR(S): 8180003: Remove sys/ prefix from poll.h and signal.h includes

[David Holmes]

Hi Mikael,

To repeat myself from:

http://mail.openjdk.java.net/pipermail/portola-dev/2017-April/000025.html

Changes look okay. I agree with the rationale.

Looking at actual implementations, linux and mac OS are trivially fine
(poll.h just includes sys/poll.h). Solaris is non-trivially fine -
poll.h does more than what sys/poll.h does, but nothing that affects our 
sources.

Thanks,
David

:)
