kpatch-build: include secsym in kpatch_mark_ignored_sections

Browse Source 
kpatch_mark_ignored_sections include .rodata.str1.1 section but does
not include its section symbol, causing its section symbol can not be
included any more in kpatch_include_standard_elements. After the
section symbol is freed in kpatch_elf_teardown, we got a segmentation
fault in kpatch_create_intermediate_sections.
