net: intel: igc_ptp: fix build for UML

Browse Source 
On a UML build, the igc_ptp driver uses CONFIG_X86_TSC for timestamp
conversion. The function that is used is not available on UML builds,
so have the function use the default system_counterval_t timestamp
instead for UML builds.

Prevents this build error on UML:

../drivers/net/ethernet/intel/igc/igc_ptp.c: In function ‘igc_device_tstamp_to_system’:
../drivers/net/ethernet/intel/igc/igc_ptp.c:777:9: error: implicit declaration of function ‘convert_art_ns_to_tsc’ [-Werror=implicit-function-declaration]
  return convert_art_ns_to_tsc(tstamp);
../drivers/net/ethernet/intel/igc/igc_ptp.c:777:9: error: incompatible types when returning type ‘int’ but ‘struct system_counterval_t’ was expected
  return convert_art_ns_to_tsc(tstamp);
