base-files: optimize init.d/boot

-uci_apply_defaults
 * set IFS for robustness
 * removed directory change to /etc/uci-defaults
 * removed variable files with ls subshell
 * removed test variable files has zero length
 * removed basename subshell
 * changed "for var" into "for glob"
 * added "commit only on changes"
-boot
 * removed quotes from echo
 * grouped commands by path
 * merged mkdir & chmod for /var/lock
 * merged mkdir & chmod for /tmp/.uci
 * removed "f flag" from symlink /tmp/resolv.conf
 * added local variable for common mount options
 * favored path test over grep filesystems
 * converted wireless test from "negative and" to "positive or"
 * remove second instance of mkdir /tmp/.uci
 * added test for /sbin/wifi
