libpam: Avoid wildcards in the SRC_URI

libpam: Avoid wildcards in the SRC_URI

Remove the wildcard from the SRC_URI.  This causes problems when you .bbappend
and add a FILESEXTRAPATHS entry.  The unpack task may be unable to find the
files to unpack leading to an error.

Avoid wildcards at all costs...
