*-flash.init: Use busybox ash
Busybox no longer has CONFIG_BASH since we are deploying bash on most
boards.  We also should clearly indicate which scripts cannot use
bashisms.

Change shebang in x230-flash.init, t430-flash.init, flash.sh to
/bin/ash.  Execute /bin/sh for interactive shells.

Move key functions needed by those scripts to initrd/etc/ash_functions.
Source ash_functions instead of functions in those scripts, so any
bashisms in other functions won't break parsing of the script in ash.
