selftest: ftrace: Fix to pick text symbols for kprobes
[ Upstream commit 5e46664703b364434a2cbda3e6988fc24ae0ced5 ]
Fix to pick text symbols for multiple kprobe testcase.
kallsyms shows text symbols with " t " or " T " but
current testcase picks all symbols including "t",
so it picks data symbols if it includes 't' (e.g. "str").
This fixes it to find symbol lines with " t " or " T "
(including spaces).
