vgasrc: ignore .node.gnu.property (binutils-2.36 support)

Modern binutils unconditionally tracks x86_64 ISA levels in intermediate
files in .note.gnu.property. Custom liker script does not handle the
section and complains about it:

    ld --gc-sections -T out/vgasrc/vgalayout.lds out/vgaccode16.o \
        out/vgaentry.o out/vgaversion.o -o out/vgarom.o
    ld: section .note.gnu.property LMA [0000000000000000,0000000000000027] \
        overlaps section .text LMA [0000000000000000,00000000000098af]

The change ignores .note* sections.
