[OE-core] [PATCH] bitbake.conf: fix distro-less failure expanding FILESPATH

[Denys Dmytriyenko]

From: Denys Dmytriyenko <denys at ti.com>

If DISTRO is not set, FILESPATH becomes littered with directories like
files/${DISTRO} etc. It won't bomb until you try to eval it - i.e.
manipulating FILESPATH directly with .= works fine, but calling e.g.
base_set_filespath() throws this:

ERROR: Failure expanding variable FILESPATH, expression was ${@blah} which
triggered exception SyntaxError: EOL while scanning string literal (FILESPATH,
line 1)
