[PATCH EDK2 v1 1/1] MdeModulePkg/BaseBmpSupportLib: Fix ColorMap issue

["wenyi,xie" <xiewenyi2@huawei.com>]

When BitPerPixel is 1,4,8, there should be a color map in bmp file. But if
the format of bmp file is error, it maybe has no color map when BitPerPixel
is 1,4,8. The condition checking now can not catch this issue.
