Upgrade fasthttp module

[cthulhu-rider]

For now the latest version of fasthttp is v1.33.0. I think I'd be useful to upgrade the used module.

I briefly ran through the changes that may affect the application:

At least we should upgrade to v1.34.0 because there was a fix without which tests sometimes fail. Beside this using v1.34.0 encountered with strange bug:

panic: context: internal error: missing cancel error

goroutine 22075 [running]:
context.(*cancelCtx).cancel(0xc000be4820, 0x90, {0x0, 0x0})
        /usr/local/go/src/context/context.go:399 +0x27e
context.propagateCancel.func1()
        /usr/local/go/src/context/context.go:281 +0xe2
created by context.propagateCancel
        /usr/local/go/src/context/context.go:278 +0x1d0

I'm not sure if the reason v1.34.0 or problem in neofs-http-gw code

Don't think it is related, but I had some context cancel propagation errors in integration test with -race flag.
