tests/tcg: Use --noexecstack with assembler files

Add the --noexecstack assembler command-line option to avoid:

/usr/bin/ld: warning: boot.o: missing .note.GNU-stack section implies executable stack
/usr/bin/ld: NOTE: This behaviour is deprecated and will be removed in a future version of the linker

which is enabled by default with current debian cross toolchains.

tests/tcg: limit the scope of the plugin tests

Running every plugin with every test is getting excessive as well as
not really improving coverage that much. Restrict the plugin tests to

for both system and user-mode. For those that aren't we need to squash
MULTIARCH_TESTS so we don't add them when they are not part of the
TESTS global.
