package/p11-kit: switch to meson build system

P11-kit has been offering a meson build since 0.23.17 (see upstream
NEWS [1]), and it is the build system described in the upstream
README.

Changes in the switch to meson:

* Explicitly enable/disable NLS.
* Explicitly enable/disable bash-completion.
* The meson build has no explicit option for libtasn1, it is required
  if trust_module is enabled.
* Add patch for meson configuration to avoid depending on systemd to
  discover install location for units, which would create a dependency
  loop.
* Check for BR2_INIT_SYSTEMD instead of BR2_PACKAGE_SYSTEMD to decide
  whether to install systemd units.

+Subject: [PATCH] meson: allow setting systemduserunitdir to break dependency
+ loop
+
+The dependency on systemd is only used to retrieve systemduserunitdir,
+not otherwise needed during build. However, p11-kit is also an
+(optional) dependency of systemd, creating a dependency loop.
+
+This patch allows setting systemduserunitdir directly to break the
+dependency loop. If set, the given value is used unconditionally
+without checking for systemd, otherwise systemd is detected as before.
