8344345: test/hotspot/gtest/x86/x86-asmtest.py has trailing whitespaces

[rm-gh-8]

Backporting JDK-8344345: test/hotspot/gtest/x86/x86-asmtest.py has trailing whitespaces.

This PR cleans up trailing whitespace in x86-asmtest.py that was introduced in commit openjdk/jdk@916694f and went undetected because jcheck's [checks "whitespace"] config doesn't cover *.py files. The trailing whitespace causes pre-commit hooks to complain during merges, forcing developers to temporarily disable hooks as a workaround.

Ran related tests on linux-x64:

make test TEST="gtest:*AssemblerX86*"

Results attached:

linux-x64-specific-test.log

Checked asmtest.out.h file created before and after the commit and they were identical:

asmtest.out.h.old.txt
asmtest.out.h.new.txt
