[PATCH v2 1/3] kconfig: print the output of expr_alloc_and() instead of printing '&&'

[Julian Braha <julianbraha@gmail.com>]

Clean up expression printing for 'select' and 'imply' (which ANDs the
select/imply targets), to properly call expr_alloc_and() and print the
output, instead of printing a literal ' && '. 

This is necessary to ensure that any '&&' at the end of those lines can
wrap properly.
