increase rlimit

Increasing FStar.UInt rlimit seems to be necessary to build on MacOS,
unrelated to `no_inline_let`.
Increasing FStar.Seq.Properties necessary with `no_inline_let`, though
I'm not sure why.
Increasing FStar.Sequence.Base necessary with `no_inline_let` on MacOS,
but wasn't necessary on Linux.
