meta: Convert getVar/getVarFlag(xxx, 1) -> (xxx, True)

Using "1" with getVar is bad coding style and "True" is preferred.
This patch is a sed over the meta directory of the form:

sed \
 -e 's:\(\.getVar([^,()]*, \)1 *):\1True):g' \
 -e 's:\(\.getVarFlag([^,()]*, [^,()]*, \)1 *):\1True):g' \
 -i `grep -ril getVar *`
