Avoid statx syscall on Android API < 30 to prevent SIGSYS crash

[sky130]

Stack trace points to okio.PosixFileSystem.variantMetadataOrNull() calling the statx syscall. On Android API 26, statx is blocked by seccomp and the kernel directly sends SIGSYS to the process. Execution never reaches the fallback lstat path because the signal terminates the app immediately.
