util/kconfig: Fix default value getter for integer options

CB:37152 was supposed to be uprev to Linux's kconfig, but it got this
one case wrong, Linux never returned "0" [1]. As a result, when an
option has default value different than 0, and it was changed to 0,
savedefconfig skips saving it. However, during the build from such
defconfig the option is assigned default value.

TEST=Set SEABIOS_DEBUG_LEVEL to 0 and see that savedefconfig writes
it to defconfig file.
