Revert "virt-result.m4: Colourize summary printings"

The colorization based on the string itself makes little to no sense as
the semantic meaning of the color (red = bad, green = good) is not
extracted from the semantics of the message:

1) If there is some additional string a 'yes' is marked yellow:

configure:       driver_modules: yes (CFLAGS='' LIBS='-ldl')

2) In some cases a 'no' is actually good:

configure:                  hal: no

3) Few good/recommended configuration options are still yellow:

configure:                 QEMU: qemu:qemu

while using 'root:root' would still be yellow.

4) fields dumping config (e.g. the warning flags line) is a giant blob
  of colored text which makes little sense

configure:        Warning Flags:  -fno-common -W -Wabsolute-value
-Waddress -Waddress-of-packed-member -Waggressive-loop-optimizations
-Wall -Wattribute-warning -Wattributes -Wbad-function-cast
-Wbool-compare -Wbool-operation -Wbuiltin-declaration-mismatch
-Wbuiltin-macro-redefined -Wcannot-profile -Wcast-align
-Wcast-align=strict -Wcast-function-type -Wchar-subscripts -Wclobbered
-Wcomment -Wcomments -Wcoverage-mismatch -Wcpp -Wdangling-else
-Wdate-time -Wdeprecated-declarations -Wdesignated-init
-Wdiscarded-array-qualifiers -Wdiscarded-qualifiers -Wdiv-by-zero
-Wdouble-promotion -Wduplicated-cond -Wduplicate-decl-speci ...

In addition if the idea is to switch to a more usable build system it
does not make sense to clutter the current one with more code.

This reverts commit 4b3ab5d2135a0dccd654491ef3a4f5b71575deae.
