perf s390
LT' relocations before '.text' section. So there exists an offset between
module base address and '.text' section, which will incur wrong symbol
resolution for modules.
Fix this bug by getting 'start' address of module's map from parsing
'/sys/modul
text_start';
2.Parse '.text' start addr from 'sys' through 'sysfs__read_ull', not
'hex2u64()';
2.Perfect code: check return value and allocated pointer by 'strdup'.

is kernel map start(no-zero), we can
get '_text' symbol of vmlinux, but we can't find the pair '_text' symbol of
kallsyms, because there is no map starting from zero. This mismatch is
incorrrect.
Fix by just ignoring these symbols before kernel start.
