Tools used within the sandbox are now copied into the
sandbox, see aosp/1531944. This caused the modified
headers_install.sh, which is no longer installed, to
point to a non-existent location.
This change adds a level of indirection. The
gen-headers_install.sh module no longer uses unifdef as
a tool, but still modifies the headers_install.sh
script, but not to point to a particular location, but
to find the unifdef tool via an environment variable,
LOC_UNIFDEF.
Next, we modify qti_generate_kernel_headers_arm and
qti_generate_kernel_headers_arm64 to need the unifdef
tool (which is copied into the sandbox for these tools).
We add a new --unifdef option to the kernel_headers.py
script so that it can find the tool in the sandbox. The
kernel_headers.py script sets the LOC_UNIFDEF
environment variable before invoking the altered
headers_install.sh script (also copied into the
sandbox).
Finally, we generate gen_headers_arm.bp and
gen_headers_arm64.bp with all of these changes.

To avoid build failures in the newer Android build systems,
run the headers_install script explicitly under 'sh'.

Disable matching of existing and generated gen_headers*.bp files.
This is done to allow some uapi headers to be added to audio
techpack.

Currently the Soong logic doesn't kick in if a change updates
headers but doesn't update gen_headers_arm*.bp files for
incremental builds. Fix the issue by making inputs to the
kernel_headers.py script as variables instead of a list.

Update comparison logic used to figure out the headers
that need to be added or removed from the corresponding
blueprint file.

This change is foundational for converting many modules that depend on kernel
headers built via the platform build system.

[rishabhb@codeaurora.org: add logic to iterate over mandatory headers
and only generate these headers if not already present in
usr/include/asm. Also export techpack uapi headers.]
