8252248: __SIGRTMAX is not declared in musl libc

[voitylov]

JDK-8252248 is in the first batch of a chain of backports for Alpine support to 11u as discussed in the mailing list. For the full set of anticipated changes please refer to the jdk-updates mailing list [1].

Compared to original changeset this backport looks cosmetically different in #ifdefs in NativeThread.c because of another code layout due to "8244224: Implementation of JEP 381: Remove the Solaris and SPARC Ports".

Testing: JCK + JTreg on Windows, Linux, Solaris, Mac without regressions.
