blktrace: convert strncpy() to strscpy_pad()
gcc-9 warns about a possibly non-terminated string copy:
kernel/trace/blktrace.c: In function 'do_blk_trace_setup':
kernel/trace/blktrace.c:527:2: error: 'strncpy' specified bound 32 equals destination size [-Werror=stringop-truncation]
Newer versions are fine here because they see the following explicit
nul-termination. Using strscpy_pad() avoids the warning and
simplifies the code a little. The padding helps give a clean
buffer to userspace.
