Fix for @repo targets in mfg create

[dwld]

Without the fix, mfg create for targets such as target.app: "@mcuboot/boot/mynewt" fails, since the path to the .manifest, .hex and .bin is wrong.

This can be fixed by using the target app's FullName() instead of Name().

[utzig]

This use of Name() in those functions has been like this for basically ever. All my MCUBoot targets look something like the one you mentioned (target.app: "@mcuboot/boot/mynewt") and I see no build issues, what errors exactly am I expected to see? Please copy some newt -ldebug ... output here.

[dwld]

Hi @utzig, thanks for your feedback. I'll gather the debug output. Perhaps my .mfg file or my targets are not correct. I just published a documentation update idea, could you perhaps check it? https://github.com/apache/mynewt-newt/pull/392 Thanks.

@utzig, here is the output of the current master newt build as it is:

Error: failed to read manifest file: open C:/Entwicklung/newt_ble_central/bin/targets/nrf52_boot/app/boot/mynewt/manifest.json: The system cannot find the path specified.

With the fix, the command works for me and outputs the following paths as its inputs:

$ newt -ldebug mfg create p_nrf52_ble 0.0.0.5

@dwld I wonder if this could be a Windows-specific issue you are seeing. Do you think you could show an example without redacting any paths? Unfortunately I don't have a Windows machine available to test this on.

Sorry for the delay. I was on parental leave and will create new logs with full paths in the next days.
