git.py source plugin: Prune remote-tracking branches when fetchingsam/git-fetch-prune
I noticed this issue when running `bst track` on a system that contained
GLIBC. The following error occurred:
[--:--:--] START [gnu-toolchain/stage2-glibc.bst]: Tracking release/2.25/master from git://git.baserock.org/delta/glibc

error: some local refs could not be updated; try running
'git remote prune origin' to remove any old, conflicting branches
git source at gnu-toolchain/stage2-glibc.bst [line 4 column 2]: Failed to fetch from remote git repository: git://git.baserock.org/delta/glibc
The issue here is that my local clone had old remote-tracking refs which
conflicted with newer upstream refs. For example, there used to be a ref
named `hlj/memcpy` which I had mirrored locally. This has been deleted
and now a ref exists named `hlj/memcpy/dpdk/master`. The new ref cannot
be pulled because Git considers it to conflict with the old one.
The solution is to use `git fetch --prune` when updating so that Git
removes any outdated remote-tracking refs before trying to create any
new ones.
