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.

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.]

Create a header library which export kernel headers.
These headers are needed by modules and userspace libraries.
