 rts: Flush eventlog in hs_init_ghc (fixes #15440)

 Without this change RTS typically doesn't flush some important
 events until the process terminates or it doesn't write them at
 all in case it terminates abnormally.

 Here is a list of such events:

 * EVENT_WALL_CLOCK_TIME
 * EVENT_OS_PROCESS_PID
 * EVENT_OS_PROCESS_PPID
 * EVENT_RTS_IDENTIFIER
 * EVENT_PROGRAM_ARGS
 * EVENT_PROGRAM_ENV
 }}}
