target/breakpoints: fix types in watchpoint_add_internal()

There was a conflict:
1. commit 2cd8ebf ("breakpoints: use 64-bit type for watchpoint mask
   and value")
2. commit 0bf3373 ("target/breakpoints: Use 'unsigned int' for
   length")

The second commit was created erlier, but merged later so the types of
`mask` and `value` became `uint32_t` in `watchpoint_add_internal()`.

This created a bug:
`WATCHPOINT_IGNORE_DATA_VALUE_MASK` is defined as `(~(uint64_t)0)`.
Truncation to uint32_t makes it so the comparisons with the constant
don't work.
