Avoid a memmove by advancing value pointer

Browse Source 
In packages, our description file contains:
key = value is here
type entries, and we passed "key " and " value is here" to our strtrim
function, causing us to always memmove the value portion to remove the
space. Since this is a throwaway buffer, do the advancing on our own before
trimming to save the need to shift memory around; "value is here" will now
be passed and strtrim will be responsible for trailing whitespace.
