util: avoid NDN_THROW_NESTED in RegexRepeatMatcher

This is a workaround for an odd crash in boost::current_exception()
on Ubuntu 25.04 (see https://github.com/boostorg/exception/issues/60)

In this case the nested exception doesn't provide any useful extra
information, so we're not losing much by simply dropping it.

Also, suppress two new errors raised by lcov 2.3.
