[instrprof] Use __{start,stop}_SECNAME on PS4 too.

Summary:
The PS4 linker seems to handle this fine.

Hi David, it seems that indeed most ELF linkers support
__{start,stop}_SECNAME, as our proprietary linker does as well.

This follows the pattern of r250679 w.r.t. the testing.

Maggie, Phillip, Paul: I've tested this with the PS4 SDK 3.5 toolchain
prerelease and it seems to work fine.
