core: cleanup data types for nm_platform_sysctl_get_int32()

Browse source 
The sysctl values in the kernel (for those values for which
nm_platform_sysctl_get_uint() is currently used) are defined as s32.
Change nm_platform_sysctl_get_uint() to nm_platform_sysctl_get_int32()
and ensure, that a matching integer type is used thoroughly.
