script: Make linux-tizen-modules-source git repo up-to-date on the same branch

If the version of linux-tizen-modules-source is different from the kernel,
the created boot image may not boot the target exactly.
This patch executes `git pull` on the linux-tizen-modules-source repo after
making the branch of linux-tizen-modules-source synced with the kernel.

If the user don't want it, just passes  "dontpull" as the last argument of
the build script. It will not execute `git pull`.
