bitbake: toaster: fix validation checks for DL_DIR and SSTATE_DIR

Validation logic on the project configuration page
prevented a user from adding ${variable} to these paths.

Update validation so a user can see a better message
when they type characters into the text inputs.
Two types of validation are implemented.

Either:

* The value should start with a "/", to allow absolute paths.

or

* The value should start with a "$", to allow bitbake
   variables like ${TOPDIR}.
