[OE-core] [PATCH] package_ipk.bbclass: Fix SRC_URI whitespace handling

[Mark Hatle]

The SRC_URI may contain whitespace, but be otherwise empty.  This can happen
in the case:

MYSRC = ""
MYSRC_arm = "file://myarm.patch"
SRC_URI += "${MYSRC}"

Unless we strip blank spaces, to determine if it is empty, we can end up
generating a "Source: " line which in invalid.  This leads to the error:

  invalid Source: field is speified in the generated CONTROL file
