* Read ELF build ids directly from the target process.

Closes #71.

A few things to consider:
* Since we read from the process memory, the process must be in
  ptrace-stop (see `test_file_id`). This changes when the build ids can
  be read. Previously they could be read without the process being
  stopped if the mapped files still existed (and were hopefully the same
  that the process was using).
* The previous implementation made some mutations to deleted mapping
  names (removing the ` (deleted)` suffix). We need to decide whether we
  still want/need this behavior. In the meantime I commented out a
  failing test assertion.

* Address review comments.

* Always remove ` (deleted)` from module names at parse time.

* Fix failing CI tests.

This test needed to be disabled due to permissions issues.

* Improve error handling of strtab and impl ModuleMemory for &[u8].

* Add tests to build id reader.

When this fails, it falls back to the previous behavior of trying to
open the mapped file name directly.

Closes #79.

Update vulnerable crate

Update cargo deny configuration and vulnerable crates

Read ELF SONAMEs directly from process memory when possible.

for similar reasons.

This creates a few duplicate dependencies, but they are only
dev-dependencies (and they will work themselves out as the `backtrace`
crate gets updated).

Update the minidump crates to 0.22
