timeout in zstd/encoder_test.go:100 on ARM Cortex-A9

[rathann]

The whole zst test takes over 120s total on an ARM Cortex-A9:

ok  	github.com/klauspost/compress/zstd	122.090s

I experimented with setting different timeout values in zstd/encoder_test.go:100 and found that 35 seconds is enough for this particular hardware, but you might want to increase it further to have some headroom for slower hardware.

Thanks for the report. Set the timeout to 2 minutes.
