[dm-crypt] [PATCH] include sys/sysmacros.h for major/minor/makedev

These functions are defined in that header, so include it when needed.
Otherwise we can get build failures like:
veritysetup-utils_loop.o: In function '_sysfs_backing_file':
utils_loop.c:(.text+0x50): undefined reference to 'minor'
utils_loop.c:(.text+0x5e): undefined reference to 'major'
veritysetup-utils_loop.o: In function 'crypt_loop_device':
utils_loop.c:(.text+0x638): undefined reference to 'major'
../lib/.libs/libcryptsetup.so: undefined reference to 'makedev'
