Minor: Launch script does not sanitise .fam category string

[csBlueChip]

Describe the bug.

If applications_user/fapname/application.fam has a category string which contains a space, the fbt script will break with Error 3

Reproduction

Compiling against FZ 7414e6d4dff582efb6ad716e8268cad03be65c87 :-

cd ~/flipperZero/official/applications_user
mkdir bc_demo
cd bc_demo
git clone https://github.com/csBlueChip/FlipperZero_plugin_howto.git ./
cd ../..
./fbt launch APPSRC=bc_demo

observe the error

Anything else?

The obvious workaround is "don't use spaces" ...although the rest of the system is quite happy with them
