[oe] [PATCH] libpam_1.1.1: remove directory preventing /var/run from being volatile

[Mats Kärrman]

The libpam make install creates a /var/run/sepermit folder that prevents
the later creation of a sym-link /var/run --> /var/volatile/run. This is
a problem because it causes additional wear to FLASH file systems.

The solution is ~equivalent to the solution applied in libpam recipes of
oe-core but v1.1.1 does not exist there and the corresponding fix was a
part of the original recipes for later versions.
