Remove q-factor weighting on Accept Header
bmcweb does not do anything with the q-factor weighting (;q=) so just
remove it from the encoding.
This is needed because routes like
"/redfish/v1/Systems/system/LogServices/EventLog/Entries/<str>/attachment"
have a check for isOctetAccepted. Even though */* is in the Accept
Header isOctetAccepted still fails due to the q-factor weighting.
On the system I tested, on firefox, Accept looks like:
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,*/*;q=0.8
The GUI reported being unable to download a AdditionalDataURI (e.g.
...attachment/)
Here is the GUI code attempting to download the additional data:
https://github.com/openbmc/webui-vue/blob/9b79a6e7e3df3d3cbaf9a7750bbe343628022026/src/views/Logs/EventLogs/EventLogs.vue#L155
https://github.com/openbmc/webui-vue/blob/9b79a6e7e3df3d3cbaf9a7750bbe343628022026/src/locales/en-US.json#L251
Today this results in a 400 Bad Request due to isOctetAccepted.
See: https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Accept
Tested:
/redfish/v1/Systems/system/LogServices/PostCodes/Entries/<str>/attachment/
and .../EventLog/Entries/<str>/attachment now return correctly.
