kallsyms: ignore __kstrtab_* and __kstrtabns_* symbols
Every EXPORT_SYMBOL creates __kstrtab_* and __kstrtabns_*, which
consumes 15-20% of the kallsyms entries.
For example, on the system built from the x86_64 defconfig,
$ cat /proc/kallsyms | wc
129527 388581 5685465
$ cat /proc/kallsyms | grep __kstrtab | wc
23489 70467 1187932
We already ignore __crc_* symbols populated by EXPORT_SYMBOL, so it
should be fine to ignore __kstrtab_* and __kstrtabns_* as well.
This makes vmlinux a bit smaller.
$ size vmlinux.before vmlinux.after
text data bss dec hex filename
22785374 8559694 1413328 32758396 1f3da7c vmlinux.before
22785374 8137806 1413328 32336508 1ed6a7c vmlinux.after
