[Meson] Add a fallback mechanism for build dependency on iniparser

The upstream of iniparser does not provide .pc or .cmake files.
Therefore, in order to distribute the development package for iniparser,
providing those files is up to the package maintainers for various
platforms. This is the reason why some platforms have the .pc file for
iniparser and others don't. To resolve this issue, this patch adds a
fallback mechanism for build dependency on iniparser to the meson build
script.
