__off_t is a kernel internal symbol, which happens to be user-visible
with glibc, but not necessarily with other C libraries such as
musl. In v4l-utils code, it's mainly used for the mmap() prototype,
but the mmap() manpage really uses off_t, not __off_t.
Switching from __off_t to off_t allows the code to build properly with
musl.
