build: Add meson build

Changes to note,
- `with_systemdsystemunitdir` and `with_tmpfilesdir` is removed since it
  is not being documented nor used in OpenBMC.
- Removed the Code coverage feature with `-DDHAVE_GCOV`, since it is not
  used and meson covers it.
- Removed `--enable-oe-sdk` for using the OpenBMC SDK. It should work
  directly with no change required.

Tested:
```
Jan 01 00:01:54 ipmid[709]: Try loading blob from persistent data
Jan 01 00:01:54 ipmid[709]: Stale blob data, resetting internals...
Jan 01 00:01:56 ipmid[709]: config loaded: /flash/bios
Jan 01 00:01:56 ipmid[709]: config loaded: /flash/image
Jan 01 00:01:56 ipmid[709]: config loaded: /flash/dummy
...
```

```
$ ls /usr/lib/blob-ipmid/
libfirmwareblob.so
libfirmwarecleanupblob.so  libversionblob.so
```

Testing the service,
```
$ echo "hello" > /tmp/test.txt
$ burn_my_bmc -command update -layout dummy -image /tmp/test.txt
Sending over the firmware image.
Opening the verification file
Committing to /flash/verify to trigger service
Calling stat on /flash/verify session to check status
running
success
Returned success
succeeded
```

On the BMC.
```
/run/initramfs$ cat dummy
hello
```
