meson: Fix yajl workaround

Browse Source 
Meson reports

  WARNING: pkgconfig variable 'cflags' not defined for dependency yajl.

which makes sense, because "cflags" is not one of the variables
reported by

  $ pkg-config --print-variables yajl

and

  $ pkg-config --variable=cflags yajl

doesn't work either.

The breakage was introduced when we switched from calling
pkg-config directly to using get_pkgconfig_variable() in 7.5.0
and, somehow, it went undetected until now.

Use "includedir", which is a proper pkg-config variable,
instead.
