[OE-core] [PATCH 1/1] generate-manifest-2.7.py: replace os.popen with os.unlink

[Robert Yang]

The os.popen function would fail (more or less) silently if the executed
program cannot be found, and here what we need is os.system not os.popen
since it doesn't use the return value, use os.unlink() and ignore
exceptions from it would be better as Chris suggested.

[YOCTO #2454]
