libblock: Fix string truncation warning

This patch does not only fix the compiler warning below. memcpy() is the
better function at this place as the terminating NUL character is never
copied here. Instead more characters will be appended to the
'logical_disk_name' later on.

../../../cpukit/libblock/src/bdpart-register.c:41:5:
warning: 'strncpy' output truncated before terminating nul copying
as many bytes from a string as its length [-Wstringop-truncation]
