fix off-by-one write in proc/cpuinfo hardware/revision parse

[soma0212]

In parse_line (src/arm/linux/cpuinfo.c) the Hardware and Revision handlers null-terminate with state->hardware[value_length] = '\0' in the branch taken when the value fits. But the length guard uses > CPUINFO_HARDWARE_VALUE_MAX (and > CPUINFO_REVISION_VALUE_MAX), so a value whose length is exactly the max still takes that branch. Those destinations are exactly MAX bytes (64 and 9), so a Hardware line with a 64-byte value, or a Revision line with a 9-byte value, writes the terminator one byte past the buffer.

Change both comparisons to >= so an equal-length value goes through the truncation path instead. That leaves the buffer full and unterminated, which is already the contract downstream code relies on (the chipset decoders read these fields with strnlen(buf, MAX)), so keeping the bound at the write site is enough and no consumer needs to change.
