btrfs-progs: convert: add missing types header

Build with musl libc needs the sys/types.h header for the dev_t type,
since this header is not included indirectly. This fixes the following
build failure:

In file included from convert/source-fs.c:23:0:
./convert/source-fs.h:112:1: error: unknown type name ‘dev_t’
 dev_t decode_dev(u32 dev);
 ^~~~~
convert/source-fs.c:31:1: error: unknown type name ‘dev_t’
 dev_t decode_dev(u32 dev)
 ^~~~~
