bitbake: utils: better_compile(): Fix line number when report errors

Browse Source 
Fixed:
- Add an error line in base.bbclass, e.g.:
  15
  16 def oe_import(d):
  17     import sys
  18     Compile error
  19     bbpath = d.getVar("BBPATH").split(":")
  [snip]

  Note the "Compile error" line, I added it for reporting errors.

  $ bitbake -p
  ERROR: Error in compiling python function in /buildarea1/lyang1/poky/meta/classes/base.bbclass, line 15:

  The code lines resulting in this error were:
       0014:    import oe.data
       0015:    for toimport in oe.data.typed_value("OE_IMPORTS", d):
       0016:        imported = __import__(toimport)
       0017:        inject(toimport.split(".", 1)[0], imported)
   *** 0018:
       0019:    return ""
       0020:
  SyntaxError: invalid syntax (base.bbclass, line 18)

  There are 2 problems:
  - The "line 15" is incorrect, it is a blank line, not the error line.
  - The "*** 0018" points to incorrect position.

  These two problems would mislead people a lot sometimes.

- Now fix it to:
  $ bitbake -p
  ERROR: Error in compiling python function in /buildarea1/lyang1/poky/meta/classes/base.bbclass, line 18:

  The code lines resulting in this error were:
       0001:def oe_import(d):
       0002:    import sys
   *** 0003:    Compile error
       0004:    bbpath = d.getVar("BBPATH").split(":")
                [snip]
  SyntaxError: invalid syntax (base.bbclass, line 18)

Please see comments in the code for more details on how it is fixed.
