Grische b4fb0fefcb build: fix empty VERSION_DIST in Netgear image versions 
Commit 4071398b13 replaced $(VERSION_DIST) in the netgear-dni and
netgear-encrypted-factory recipes with $(shell cat $(VERSION_DIST) | sed
...) to turn whitespace into dashes. VERSION_DIST holds the distribution
name such as "OpenWrt" and not a file name, so cat fails with "No such
file or directory" and the expansion is always empty.

The change was meant to let a distribution name with a space, such as
"ColVisTec AG", pass through the argument parsing of
netgear-encrypted-factory.py as "ColVisTec-AG". What it produced instead
was an empty string for every distribution name, including the one it
was written for. The build error went away only because an empty string
contains no whitespace.

Since then, the DNI header of the Netgear images carries
"version:V.r12345" instead of "version:VOpenWrt.r12345", and the
encrypted factory images get "V1.0.0.0..r12345" with an empty field
between two dots instead of "V1.0.0.0.OpenWrt.r12345".

The distribution name has been part of the Netgear version string since
commit 6d2fa1c896 added the first WNDR3700 factory image in 2009, and
the encrypted factory recipe used it from its introduction in commit
efca76ffce.

Use $(subst $(space),-,$(VERSION_DIST)) instead, which restores the
distribution name and still replaces spaces with dashes as intended.

Fixes: 4071398b13 ("build: escape whitespaces in VERSION_DIST for Netgear images")
