Refine imxlinux_example.sh build script

Now the build script are refined to use parameter for different option:
Usage: ./scripts/examples/imxlinux_example.sh -s|--src <src folder>
-o|--out <out folder> [-d|--debug] [-n|--no-init] [-t|--trusty]
        -s, --src       Source folder
        -o, --out       Output folder
        -d, --debug     Debug build (optional)
        -n, --no-init   No init mode (optional)
        -t, --trusty    Build with Trusty OS backed security enhancement (optional)

example: ./scripts/examples/imxlinux_example.sh -s examples/chip-tool
-o out -dnt  #will build examples/chip-tool to out/ folder with debug
build and skip init and use Trusty OS.
