[PATCH 3/4] tests/guest-debug: Support passing arguments to the GDB test script

[Gustavo Romero]

This commit adds a new option to run-test.py, --test-args, which can
be used to pass arguments to the GDB test script specified by the --test
option. The arguments passed are in the key=value form, and multiple
pairs can be passed, separated by a space. For example:

run-test.py [...] --test <GDB_TEST_SCRIPT> --test-args v0="string" v1=10

The 'v0' and 'v1' variables will then be available in the GDB test
script, like this:

print(v0)
print(v1)
