### Problem description
<!-- Describe the bug that you fixed/feature request that you
implemented, or link to an existing issue describing it -->
Implement a Linux backend for the ProcessMemoryProvider plugin.
### Implementation description
<!-- Explain what you did to correct the problem -->
Most of the provider code is the same between Windows and Linux. The
primary differences are:
- enumerate PIDs in `/proc/` to get the process list
- use `/proc/<PID>/cmdline` as the process name
- parse `/proc/<PID>/maps` to get the module list
- reading/writing from memory is done using
`process_vm_readv`/`process_vm_writev`
NOTE: `sudo setcap CAP_SYS_PTRACE=+eip build/imhex` must be run to give
the binary permission to read another process' memory. Running as root
user should also work but I would not recommend it.
### Additional things
The existing translations keys no longer match since I moved the plugin
from `windows` to `builtin`.
I'm not well versed in C++ so I attempted to keep my changes rather
simple. Feedback is very welcome.

Compiler when compiling doesn't use them in those cases and emit a
warning, which is turned into an error by `-Werror`. Unfortunately,
CPack doesn't expose the logic it uses for stripping binaries.
