PID argument as int32 type, not as uint32:

 - "SetPerceptible" (u) -> (i)
 - "SetPlatformSwap" (u) -> (i)

The reason for the change is following:

 - Different signal handlers in memory module use different type
   for PID argument (eg. "SetMemLimit" uses (i), "SetPerceptible"
   and "SetPlatformSwap" use (u))

 - PID is already of int32 type in the most of resourced D-Bus
   functions

 - Listed functions already use int32 in selected Tizen Product

Note: The type is not compatible with D-Bus' spec GetUnixProcessID
      (which expects uint32).  Int32 PID is Tizen's system's specific.

Build resourced-light with a separate spec

Due to limitations of RPM it is impossible to build two RPM packages
containing files with different content and the same name. To work
around this limitation we create a separate spec in the repository to
avoid renaming binaries in %post scripts, which messes the RPM database
and makes it impossible to discover the origin of the binary.
