fix(rvlite): use platform-specific errno on macOS/BSD (fixes #174)

Browse source 
rvlite's writer_lease.rs used __errno_location (Linux libc) under a
generic #[cfg(unix)] guard, causing link failures on macOS where the
equivalent is __error. Split the extern and wrapper into separate
#[cfg(target_os)] blocks matching the pattern already used in
rvf-runtime/src/locking.rs.

Closes #174
