kselftest: ftrace: Fix to compare a zero-filled hex value
Fix to compare a zero-filled hexadecimal value with a part of
string of long hexadecimal value.
In check_types(), the last part of testcase compares with
the hex value formatted by "%x" with a part of a string of
long hex value (trimmed by tail -c and head -c). However,
if that part of long hex value contains zero (e.g. "05" of
"a3082059"), printf generated value (e.g. "5") is diffrent
string, and the test case failed.
To fix this, pass "%02x" instead of "%x" to printf.
