An invalid executable may claim to have a data section bigger than the executable, causing readData in searchMagic to hit EOF. Since readData suppresses all EOF errors, searchData would keep attempting to search through a potentially huge "section" despite readData continuously failing. Fix by suppressing EOF only on partial read. If nothing is read, allow EOF. Note that most of the admittedly tedious EOF handling in this package is around ensuring we return errNotGoExe in most cases. This was discovered by the new fuzz test. This fuzz test was inspired by #69066, though it has not found that specific bug.
