Add ability to test UMTS AKA, by f_gmm_attach() with flags to select UMTS AKA
and to respond to it with GSM AKA SRES.
Add TC_attach_umts_aka_umts_res and TC_attach_umts_aka_gsm_sres.
Change existing TC_attach_* to also call f_gmm_attach(). (Actually,
f_gmm_attach() is almost exactly the previous TC_attach function body.)
osmo-sgsn change I36807bad3bc55c0030d4f09cb2c369714f24bec7 will implement
proper handling of GSM AKA response and make TC_attach_umts_aka_gsm_sres pass.

'make clean' as generated by ttcn3_makefilegen removes all *.log files, which
of course cleans out expected-results.log, which should not happen. Since this
is a junit XML file, rename the suffix to .xml.
