[PATCH] meson: use built-in 'modules' helper for python dependencies

[PATCH] meson: use built-in 'modules' helper for python dependencies

[luca.boccassi]

From: Luca Boccassi <bluca@debian.org>

We now require Meson 0.53 or later, so we can use this feature introduced
in 0.51. This also fixes a build failure on SUSE Leap 15.6.

@Luca
The patch lgtm, but could you develop on what was wrong with SUSE?

@Kevin.
Just a note, this patch is probably not relevant to 21.11 as the
switch to meson 0.53.2 was done in 22.11.

The separate manual check is causing it to pick a different
non-default python3 version, which doesn't have elftools installed,
which breaks the meson run:
