Fix mktemp orphaned file in strace .init script

[Copilot]

The .init script creates a temp file with mktemp, appends .o to the variable, then only removes the .o file—leaving the original mktemp file orphaned in /tmp.

Changes:

• Use mktemp --suffix=.o to create the file with the extension atomically

Before:

ASM=$(mktemp).o  # Creates /tmp/tmp.abc123, assigns /tmp/tmp.abc123.o
rm $ASM          # Removes /tmp/tmp.abc123.o, orphans /tmp/tmp.abc123

After:

ASM=$(mktemp --suffix=.o)  # Creates /tmp/tmp.abc123.o directly
rm $ASM                     # Removes /tmp/tmp.abc123.o completely

<issue_title>mktemp residue in "Tracing Syscalls" build script</issue_title>
<issue_description>In the .init script for Tracing Syscalls, mktemp leaves an orphaned file in /tmp:

ASM=$(mktemp).o
...
rm $ASM

The rm command only targets the .o file, leaving the original empty file created by mktemp behind. Is this intentional?

Proposed Fix:
ASM=$(mktemp --suffix=.o)</issue_description>
