This firmware is not meant to be executed on the host machine, so
unset its executable bit. Noticed by lintian.
While at it, teach stage1 builds to recover from interrupted builds by
ensuring *stage1.bin are not present until all of the relevant
commands have been run.

Use anchored filenames and wildcards to make it easier to keep the
.gitignore file up to date with future code changes.
The entries are more precise now:
* ‘git add .’ will not start tracking the src/usbboot binary
* ‘git ls-files -i --exclude-standard’ will not list
xburst_stage1/Makefile and xburst_stage2/Makefile as mistakenly
tracked.
