Subject: bitbake: bitbake: build.py: create separate function for shell trap
 creation code

Currently, the shell trap code was created in exec_func_shell(). Split
the function so that we can create the code separately.

Also, some whitespaces were automatically deleted by my editor. Since
this is not necessarily a bad thing, leave these changes too.

(Bitbake rev: c712e622d20c61a07c9c172b60e9dc6beae14197)
