[shell] Enable "shell" command even when BANNER_TIMEOUT is zero

Browse Source 
Setting BANNER_TIMEOUT to zero removes the only symbol reference to
shell.o, causing the "shell" command to become unavailable.

Add SHELL_CMD in config/general.h (enabled by default) which will
explicitly drag in shell.o regardless of the value of BANNER_TIMEOUT.
