Arnd Bergmann e264abeaf9 pstore: Remove bogus format string definition
The pstore conversion to timespec64 introduces its own method of passing
seconds into sscanf() and sprintf() type functions to work around the
timespec64 definition on 64-bit systems that redefine it to 'timespec'.

That hack is now finally getting removed, but that means we get a (harmless)
warning once both patches are merged:

fs/pstore/ram.c: In function 'ramoops_read_kmsg_hdr':
fs/pstore/ram.c:39:29: error: format '%ld' expects argument of type 'long int *', but argument 3 has type 'time64_t *' {aka 'long long int *'} [-Werror=format=]
 #define RAMOOPS_KERNMSG_HDR "===="
                             ^~~~~~
fs/pstore/ram.c:167:21: note: in expansion of macro 'RAMOOPS_KERNMSG_HDR'

This removes the pstore specific workaround and uses the same method that
we have in place for all other functions that print a timespec64.

Related to this, I found that the kasprintf() output contains an incorrect
nanosecond values for any number starting with zeroes, and I adapt the
format string accordingly.
