Some perf-probe commands do symbol_init() but doesn't do exit call.
This fixes that to call symbol_exit() and releases machine if needed.
This also merges init_vmlinux() and init_user_exec() because both of
them are doing similar things. (init_user_exec() just skips init
vmlinux related symbol maps)
Changes from v2:
- Not to set symbol_conf.try_vmlinux_path in init_symbol_maps()
