include rules don't handle files with spaces in the name

[Jamie Strandboge]

$ mkdir '/tmp/foo bar'

$ echo 'profile test { include "/tmp/foo bar" }' | apparmor_parser -QTK
AppArmor parser error, in stdin line 1: Found unexpected character: '"'
"[1]

$ echo 'profile test { include "/tmp/foo\ bar" }' | apparmor_parser -QTK
AppArmor parser error, in stdin line 1: Could not open '/tmp/foo\'
"[1]

When fixing this, please also adjust utils/apparmor/regex.py (search for this bug number).
