merge binaries bmcweb and bmcwebd

Solution to reduce compressed rofs size.

Conclusion: The compiler is better at reducing binary size than the rofs
compression is at deduplicating sections of already compiled binaries,
in the case of bmcweb.

What's been changed?

`bmcweb` and `bmcwebd` have been merged into `bmcweb`.
The webserver can be started with `bmcweb daemon`.

Commands used to check size

```
wc -c build/s8030/tmp/work/*-openbmc-linux-gnueabi/obmc-phosphor-image/1.0/obmc-phosphor-image-1.0/static/image-rofs

wc -c build/s8030/tmp/deploy/images/s8030/image-rofs

xz -c build/s8030/tmp/work/*-openbmc-linux-gnueabi/obmc-phosphor-image/1.0/rootfs/bin/bmcweb | wc -c

xz -c build/s8030/tmp/work/*-openbmc-linux-gnueabi/obmc-phosphor-image/1.0/rootfs/usr/libexec/bmcwebd | wc -c

Before patch:
```
image-rofs compressed size:
25526272 build/s8030/tmp/work/s8030-openbmc-linux-gnueabi/obmc-phosphor-image/1.0/obmc-phosphor-image-1.0/static/image-rofs

bmcweb cli

bmcwebd

```

After patch:
```
image-rofs compressed size:
25477120 build/s8030/tmp/work/s8030-openbmc-linux-gnueabi/obmc-phosphor-image/1.0/obmc-phosphor-image-1.0/static/image-rofs
rootfs
25477120 build/s8030/tmp/deploy/images/s8030/image-rofs
bmcweb cli
96
bmcwebd
1059556
```

Calculating the difference in compressed rofs

25526272 - 25477120 = 49152

which is around 0.2% in terms of the total image but around 4.6% in
terms of bmcwebd binary.

Tested: on yosemite4 qemu

`bmcweb` cli interactions work as before.
