etmsync Pirelli IMEI retrieval: fix poor use of printf()
Bug reported by Vadim Yanitskiy <fixeria@osmocom.org>: the construct
where a static-allocated string was passed to printf() without any
format arguments causes newer compilers to report a security problem.
Given that formatted output is not needed here, just fixed string
output, change printf() to fputs(), and direct the error message
to stderr while at it.
