libcamera: Avoid build break in signature recalculation

The signature recalculation task can fail:
```
/.../build/tmp/work/armv8a-poky-linux/libcamera/1_0.0.4-r0/temp/run.do_recalculate_ipa_signatures_package.937421: line 154: /.../build/tmp/work/armv8a-poky-linux/libcamera/1_0.0.4-r0/git/src/ipa/ipa-sign-install.sh: No such file or directory
```

This happens whenever ${S} is removed and packages are retrieved from
sstate cache.

Instead of trying to fix the task, avoid the issue altogether by
performing the signature recalculation directly in do_package.
