internal/process.h: add a no-warning simple wrapper for fork(2)
As fork(2) is deprecated, its calls must be guarded by
`COMPILER_WARNING_IGNORED(-Wdeprecated-declarations)`.
All usages of fork(2) in process have been alread guarded. A new call
to fork(2) was added in ruby.c with f22c4ff359498ab342e4b6d6feb21af6004ee270.
This caused a build failure on Solaris 11.
It may hide a bug to guard big code unnecessarily, so this change
introduces a simple wrapper "rb_fork" whose definition is guarded, and
replaces all calls to fork(2) with the wrapper function.
