libipt: check section boundaries in pt_section_read() When reading from a mapped section, we perform all kinds of overflow checks in the various read functions. And we still missed an overflow on systems with 32-bit pointers. Move the check to pt_section_read() where we check the requested offset against the section size. Also truncate the read request there, if necessary. This fixes the overflow on systems with 32-bit pointers.

libipt: skd010/skd014
SKD010: Intel(R) PT FUP May be Dropped After OVF.
Some Intel PT (Intel Processor Trace) OVF (Overflow) packets may not
be followed by a FUP (Flow Update Packet) or TIP.PGE (Target IP
Packet, Packet Generation Enable).
Same as SKD014.
