scripts: headers_install.sh: Normalize __ASSEMBLER__ to __ASSEMBLY__
There is an ongoing effort to replace the usage of __ASSEMBLY__ with
__ASSEMBLER__ throughout the kernel tree, see for example
commit 287d163322b7 ("arm64: Replace __ASSEMBLY__ with __ASSEMBLER__ in
non-uapi headers"). The latter is automatically provided by all compilers
and preprocessors supported by the kernel, so the explicit definitions
of __ASSEMBLY__ can be removed.
However the UAPI headers might be used with non-GCC-compatible
compilers, which do not define __ASSEMBLER__ automatically.
So this migration may break users. Also during the migration phase, the
UAPI headers will use a mix of *both* __ASSEMBLY__ and __ASSEMBLER__ at
the same time, which is ugly and inconsistent.
For now make sure that the exported UAPI headers consistently use
__ASSEMBLY__ as before.
