[L] Change in osmo-hnbgw[master]: move main() to separate file

neels has uploaded this change for review. ( https://gerrit.osmocom.org/c/osmo-hnbgw/+/32620 ) Change subject: move main() to separate file ...................................................................... move main() to separate file Conform to recent osmocom practice by having an osmo_hnbgw_main.c file for main() and its immediate infrastructure. Prepares for adding a non-installed libhnbgw.la -- which must not contain a main() function -- so that linking regression tests is easy. Separating to a new file seems appropriate because hnbgw.c has gathered a bunch of stuff that is not strictly main() related / might be useful to access in a C test.
