process.c (rb_f_exec): pause MJIT before replacing process

Non-parallel "make test-spec" caused
spec/ruby/core/process/wait2_spec.rb failures because mspec
uses "exec" in single-process mode, so there's no chance
the post-exec state could know about the MJIT child process
from its pre-exec state.

[ruby-core:87846] [Bug #14867]
