[OE-core] [PATCH 1/1] apt-native: fix the creation of apt.conf.sample

[Hongxu Jia]

1.The file of "apt.conf.sample" is in the outdir, and outdir is assigned
by "os.path.join" with the params of ${D}, ${sysconfdir} and "apt". But
${sysconfdir} is an absolute dir and that let ${D} be discarded.

The following is the help on function os.path.join(a, *p):
     Join two or more pathname components, inserting '/' as needed.
     If any component is an absolute path, all previous path components
     will be discarded.
Use oe.path.join instead which don't have this problem.

2. Create apt.conf.sample if it doesn't exist.
