update flash_ts100_linux.sh

Browse Source 
Change to more generic /bin/sh script

* added support for using on shells that don't have UID variable; uses UID if it's available and calls "id -u" when it's not
* modified quoting as recommended by shellcheck
* changed to not use "$?" to check for failure. Now uses "if ! (command); then (fail condition); fi" for when a command fails
