[meta-oe] mariadb: skip failing test on musl

There is a timezone related ptest that fails using musl-libc.
This has been reported to the mariadb developers[1], who came up with
the backported patch that's the subject of this change.

This patch skips the timezone related tests with musl, in case the
testcase uses a timezone that behaves differently with musl than on
other platforms.
