Andrew GunnersonandGitHub a0171e3a9b build: allow inotify on Android amd64 (ref #8710 ) (#10783 )

ad0044fec8 previously disabled it due to
seccomp crashes. This was caused by `golang.org/x/sys`'s
`unix.EpollWait` function using the `epoll_wait` syscall instead of the
`epoll_pwait` syscall. bionic libc implements the `epoll_wait` C wrapper
function in terms of the `epoll_pwait` syscall, so this never affected C
code.

`golang.org/x/sys` switched to the `epoll_pwait` syscall in 2016, but
only for arm64. As of v0.47.0, it now uses `epoll_pwait` for all
architectures.

Upstream bug: https://github.com/golang/go/issues/80080
Upstream fix: https://go-review.googlesource.com/c/sys/+/792700
Upstream arm64 fix from 2016:
https://go-review.googlesource.com/c/sys/+/21971

---

With this change, Syncthing no longer crashes when inotify is allowed
and enabled in the Android emulator when run inside an app context. (The
seccomp policies do not affect execution under `adb shell`.)

This is the crash that occurs if inotify is enabled without the v0.47.0
