bitbake: main: Remove unneeded float()

There is already a type=float, so the float() is not needed, which also makes
the error clearer:

$ export BB_SERVER_TIMEOUT=10000AA
With float():
$ bitbake quilt-native
[snip]
ValueError: could not convert string to float: '10000AA'

Without float():
$ bitbake quilt-native
[snip]
optparse.OptionValueError: option --idle-timeout: invalid floating-point value: '10000AA'

The second one tells clearly where is wrong.
