Clarify the use of SIGUSR1 for forcing crash dumps
The crash_dump document mentions indirectly that delivering a SIGUSR1 to a
running emulator process can force it to crash dump. Clarify that text to
make it clear SIGUSR1 can be used for that purpose, and also add a similar
note about using SIGUSR1 to the erl documentation.
