Revert "Roll src/native_client ff15c51d2078..908d9f47b1b2 (11 commits)"

This reverts commit af508ec60f2a4041b59283191c53765941bb171b.

Reason for revert:
This probably causes a bot failure by breaking the deterministic build.
https://ci.chromium.org/p/chromium/builders/luci.chromium.ci/Deterministic%20Linux%20%28dbg%29/5099
https://ci.chromium.org/p/chromium/builders/luci.chromium.ci/Deterministic%20Linux/20483

Note that there's a time gap between the roll itself and the breakage
due to a cache contamination.
