meson: handle missing xkbcomp.pc better 

Applying get_pkgconfig_variable() to a not-found dependency was always
documented as an error, but meson 0.49 now actually raises an error[1]:

  meson.build:110:4: ERROR:  'xkbcomp' is not a pkgconfig dependency

Check xkbcomp_dep is a suitable dependency type before applying
get_pkgconfig_variable() to it.

[1] but this is more by accident than design (see the discusssion at [2]
et seq.), so who knows where things will come to rest...
