[PATCH] buildtools/get-test-suites.py: muti-line macros

[Marat Khalili <marat.khalili@huawei.com>]

Test list is currently generated by scanning all files for macros
starting with `REGISTER_` and ending with `_TEST`. Unfortunately, this
was done line-by-line, and macros split into several lines were silently
ignored resulting in tests being excluded from test suites without any
warning.

Make regular expression multiline, capturing everything until the
closing parenthesis. (There should be no nested parentheses due to the
nature of the arguments these macros accept.)

The rest of the functionality stays the same. The result was manually
compared to be identical to the previous version.
