Disable parallel testing for 'rust/compile/nr2/compile.exp' [PR119508]

Browse source 
..., using the standard idiom.  This '*.exp' file doesn't adhere to the
parallel testing protocol as defined in 'gcc/testsuite/lib/gcc-defs.exp'.

This also restores proper behavior for '*.exp' files executing after (!) this
one, which erroneously caused hundreds or even thousands of individual test
cases get duplicated vs. skipped, randomly, depending on the '-jN' level.

	* rust/compile/nr2/compile.exp: Disable parallel testing.
