`dump_syms` fails to write symbol file without knowing how to convert
the ELF `e_machine` field to a string.
Use "riscv" as the value because ELF `e_machine` does not distinguish
between 32 bit and 64 bit RISC-V.
Test: run `dump_syms` on the libc++ that's shipped with the Clang
toolchain, or any other riscv binary: `./dump_syms -r -n libc++.so -o
Fuchsia <clang_path>/lib/riscv64-unknown-fuchsia/libc++.so.2.0`

`NXFindBestFatArch` is deprecated in macOS 13. We use this when an
architecture is passed in via the `-a` flag. Unfortunately, neither
of the potential replacements can help with this use case:
- `macho_for_each_slice` as suggested in a reply to FB11955188 just
enumerates slices, without the logic for inexact matches (for example,
x86_64h -> x86_64 or arm64e -> arm64).
- `macho_best_slice` as recommended by the deprecation notice only
supports finding a suitable slice to run on the local machine.
We could adapt the logic in `NXFindBestFatArch` but it gets quite
complex for some architectures. Instead, this change adapts the
`NXFindBestFatArch` polyfill used in `dump_syms_mac` for Linux, which
returns an exact match if possible, and the first slice that matches
the requested CPU type otherwise. I think this is probably Good
Enough for most cases; if not, we can try porting the x86_64 and ARM
logic and falling back to this for the rest.

Previously, dump_syms always used the basename of the on-disk file as
the Breakpad module name and required that the on-disk filename of the dSYM and binary file match, or it would exit with an error.
Build automation often uses filenames unrelated to the Breakpad module
name, so this CL adds a new optional "-n MODULE" argument to Mac
dump_syms that allows passing in the Breakpad module name from outside.
In this case, the basename of the on-disk file(s) is ignored and
no longer required to match.

to doing an exact* match if NXFindBestFatArch fails.
* "Exact" meaning with CPU_SUBTYPE_MASK now masked off. But
libmacho/arch.c calls that exact too, so I'm just going to go with it.
