This reduces duplication of the split lock mitigation path.
Additionally, it allows extending the functionality of procsysctl into
also getting the split lock mitigation state.
The platform profile lives in /sys/firmware/acpi/platform_profile. The
desiredprof and defaultprof options correspond to the values for the
platform profile set when gamescope begins and ends, respectively.
HACK: The platform profile may restrict what values the governor can
take, so we choose to set the governor before the platform profile in
order to store the correct default governor, and restore the platform
profile before the governor. This is done to maximize correctness after
restoration, but it can cause issues if the previous platform profile
restricts the governor.
TODO: Save all the state we care about before any of it is changed. In
thsi case, we should set (and restore) the platform profile before the
governor.

Not all distributions install non-system binaries into /usr/bin. For
example, NixOS installs packages to /nix/store using a unique hash
generated from the inputs used to build it:
/nix/store/jld7jh3ilvbg91zvn1bdyawfc55b9jk8-polkit-0.118-bin/bin/pkexec
Specify the include directory in the link_daemon_common dependency
and thus everything that includes that as a dependency will get
the proper include directory automatically.
