[PATCH] kbuild: uapi: Drop check_config()

["Thomas Weißschuh" <thomas.weissschuh@linutronix.de>]

headers_install.sh already tests for CONFIG symbols. It does so in a
more comprehensive way, by only checking for references in code and
also running even if CONFIG_UAPI_HEADER_TEST is disabled.
And check_config() has been disabled any case.

Drop the pointless check.
