base: Improve module import error message

Turn:

ERROR: Unable to parse Var <OE_IMPORTED[:=]>
Traceback (most recent call last):
  File "Var <OE_IMPORTED[:=]>", line 1, in <module>
  File "/media/build1/poky/meta/classes/base.bbclass", line 35, in oe_import(d=<bb.data_smart.DataSmart object at 0x7f1d941ad208>):

             inject(toimport.split(".", 1)[0], imported)
  File "/media/build1/poky/meta/lib/oe/sstatesig.py", line 267, in <module>:

    >class SignatureGeneratorOEEquivHash(SignatureGeneratorOEBasicHashMixIn, bb.siggen.SignatureGeneratorUniHashMixIn, bb.siggen.SignatureGeneratorBasicHash):
         name = "OEEquivHash"
bb.data_smart.ExpansionError: Failure expanding variable OE_IMPORTED[:=], expression was ${@oe_import(d)} which triggered exception AttributeError: module 'bb.siggen' has no attribute 'SignatureGeneratorUniHashMixIn'

into:
ERROR: Error importing OE modules: module 'bb.siggen' has no attribute 'SignatureGeneratorUniHashMixIn'

which can then trigger a version mismatch error message.
