selftests: defer: Allow spaces in arguments of deferred commands

Browse Source 
Currently the way deferred commands are stored and invoked causes any
whitespace to act as an argument separator when the command is executed.
To make it possible to use spaces in deferred commands, store the commands
quoted, and then eval the string prior to execution.
