zgetdump: Replace strncpy() with memcpy()

Browse Source 
We can safely replace strncpy() with memcpy() here and get rid of the
following compile warnings:

dfi_s390mv.c: In function ‘set_magic_numbers’:
dfi_s390mv.c:570:3: warning: ‘strncpy’ output truncated before
terminating nul copying 7 bytes fr om a string of the same length
[-Wstringop-truncation]
   strncpy(l.dumper_magic, DF_S390_DUMPER_MAGIC_MV_EXT, 7);
   ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
dfi_s390mv.c:573:3: warning: ‘strncpy’ output truncated before
terminating nul copying 7 bytes fr om a string of the same length
[-Wstringop-truncation]
   strncpy(l.dumper_magic, DF_S390_DUMPER_MAGIC_MV, 7);
   ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
