locks: tidy lock acquisition

Combine the check+create done in each script. (The original functions
are still callable as before, but a new combined `Aquire_lockfile`
function can be called instead, as now used).

Note, a further simplification could be done in removing the passing of
the lock filename in as a parameter since every use of the functions is
with ".lock". The lock functions already have a fallback to ".build/lock"
though. Checking the history, the fallback used to be for a system wide
lock, which was then replaced with this config-tree specific one. As long
as that is not used implicitly by 3rd-party hooks then surely we are free
to change the fallback to ".lock" and further remove passing in a name as
a param...?
