Makefile.flags: use all cflags for crypt and rt checks
To check if libcrypt and librt are available, we check if we can
compile and link a simple test program.
These checks do not match the actual linking if CONFIG_STATIC is enabled.
For CONFIG_STATIC, CFLAGS_busybox is set to -static. The checks don't use
CFLAGS_busybox and detect a shared libcrypt or librt. If we link busybox
later and we have no static libcrypt or librt, linking will fail.
Update the libcrypt and librt checks to use CFLAGS_busybox.
