procd: optimize /sbin/reload_config

Browse Source 
* define variables, checksum tool may change
* change into /etc/config directory to avoid basenaming
* use mktemp to create tempory directory and verify
* use "exe|while" over "for subshell" to avoid basenaming
* favored "awk" over "grep+cut"
* cleaned up ubus call
* remove tempdir
