Christian Marangi 5f8dab35e3 target: fix kernel_menuconfig with external feed overwriting generic
In the case where an external feed overwrite the generic target
directory, for kernel_menuconfig the kconfig.pl use the GENERIC_PLATFORM_DIR
variable to search for the config-filter file.

The config-filter file is a file to exclude some kernel config from the
final target config file and doesn't depend on specific kernel version.
Also it's generic enough and it's possible to use the TOPDIR generic
target instead of requiring the external target feed to provide one.

To fix the kernel_menuconfig and prevent external feed from having to
duplicate this additional file, use the TOPDIR generic target as
fallback if the external target feed doesn't provide one.

References: PCF-1881
Fixes: e4635d24b2 ("target: introduce default location for external target linux generic")
