[OE-core] [PATCH] sanity: check_perl_modules bug fix

[Zheng Ruoqin]

Fix Python3 TypeError error in check_perl_modules:

Executing bitbake, the following error message will be throwed:

  File ".../poky/meta/classes/sanity.bbclass", line
979, in check_sanity_eventhandler
    check_sanity(sanity_data)
  File ".../poky/meta/classes/sanity.bbclass", line
943, in check_sanity
    check_sanity_version_change(status, sanity_data)
  File ".../poky/meta/classes/sanity.bbclass", line
637, in check_sanity_version_change
    status.addresult(check_perl_modules(d))
  File ".../poky/meta/classes/sanity.bbclass", line
563, in check_perl_modules
    errresult += e.output
TypeError: must be str, not bytes

So here, transfer e.output from bytes to str.
