Bumped bitvec don't pass build invoked with make check

[michalfita]

The symptom:

error[E0277]: the trait bound `LocalBits: bitvec::store::BitStore` is not satisfied
  --> libs/kerla_utils/bitmap_allocator.rs:8:38
   |
8  |     bitmap: spin::Mutex<&'static mut BitSlice<Lsb0, u8>>,
   |                                      ^^^^^^^^^^^^^^^^^^ the trait `bitvec::store::BitStore` is not implemented for `LocalBits`
   |
note: required by a bound in `bitvec::slice::BitSlice`
  --> /home/manveru/.cargo/registry/src/github.com-1ecc6299db9ec823/bitvec-1.0.0/src/slice.rs:62:5
