Update the .travis.yml file copied from the latest ruby_3_3 branch
<5124f9ac7513eb590c37717337c430cb93caa151>.

Skip the test_interrupt_in_other_thread test failing on Travis arm32.
The failing test is not a new issue. It had already been skipped in .travis.yml
before updating .travis.yml.
https://github.com/ruby/ruby/blob/7b05cb8dbbd637910757f402e64da3908b4bb809/.travis.yml#L99-L101

Note that RUBY_PLATFORM is "armv8l-linux-eabihf" on Travis arm32 pipeline.
And the readline was deleted in both master and ruby_3_3 branches.

So, we only need this commit on ruby_3_2 and older Ruby version branches.

	Memory leak with TracePoint on bmethod

	[Bug #20194]

	When disabling the TracePoint on bmethod, the hooks list is not freed.

	For example:

	    obj = Object.new
	    obj.define_singleton_method(:foo) {}
	    bmethod = obj.method(:foo)
	    tp = TracePoint.new(:return) {}

	    10.times do
	      100_000.times do
	        tp.enable(target: bmethod) {}
	      end

	      puts `ps -o rss= -p #{$$}`

	Fix crash when checking symbol encoding

	[Bug #20245]

	We sometimes pass in a fake string to sym_check_asciionly. This can crash
	if sym_check_asciionly raises because it creates a CFP with the fake
	string as the receiver which will crash if GC tries to mark the CFP.

	For example, the following script crashes:

	    GC.stress = true
	    Object.const_defined?("\xC3")

	[Bug #19592] Fix ext/Setup support

	After [1], using ext/Setup to link some, but not all extensions failed
	during linking. I did not know about this option, and had assumed that
	only `--with-static-linked-ext` builds can include statically linked
	extensions.

	Include the support code for statically linked extensions in all
	configurations like before [1]. Initialize the table lazily to minimize
	footprint on builds that have no statically linked extensions.
