[OE-core] [PATCH 1/3] man-pages/shadow: resolve man pages confliction

[Hongxu Jia]

Invoke smart/rpm to install man-pages and shadow-doc, there
is a build failure:
...
|error: file /usr/share/man/man5/passwd.5 from install of
shadow-doc-4.2.1-r0.0.core2_64 conflicts with file from
package man-pages-3.70-r0.0.core2_64
|error: file /usr/share/man/man3/getspnam.3 from install of
shadow-doc-4.2.1-r0.0.core2_64 conflicts with file from
package man-pages-3.70-r0.0.core2_64
...
Use alternatives mechanism to fix it.

As README in man-pages said: "Note that sometimes these
pages are duplicates of pages also distributed in other
packages. Be careful not to overwrite more up-to-date
versions. So we set man-pages with lower priority.
