[NFC] Generate separate tables via macro (#137)
This is a non functional change, it allows:
 - Getting rid of `unix_features_aggregator`
 - Have a single blob describing the features
 - Fix wrong mocking of `hwcaps`

Downside: abuse of macros makes the code slightly magical and harder to understand.
It think it's still an improvement over the current situation as there's less repetition and less chances to get something wrong.

powerpc: Add AT_PLATFORM and AT_BASE_PLATFORM
Some PowerPC machines can operate in a mode that appears different
to a process than the actual hardware. AT_PLATFORM indicates the
supported instruction set and AT_BASE_PLATFORM indicates the
actual microarchitecture of the hardware.

hwcaps: Change uint32_t to unsigned long
getauxval() returns an unsigned long which can be defined to be
more than 32 bits so don't force the result into a uint32_t.
