[U-Boot] [RFC PATCH v2 05/12] Makefile: Fix tests for CONFIG_SPL_LOAD_FIT and CONFIG_SPL_FIT_GENERATOR

[Jean-Jacques Hiblot]

The current tests do to handle well the cases where those variables are not
defined. When CONFIG_SPL_LOAD_FIT is not defined, U_BOOT_ITS gets defined
as an empty string.
Fixing it by using intermediate variables with the quotes removed
