[non-Windows] vcpkg install fails from within a path containing spaces (parse_shasum_output)

[past-due]

1. Clone the vcpkg repo into a path containing one or more spaces
2. ./bootstrap-vcpkg.sh
3. Run vcpkg install <any port>

(Abbreviated example log output):

The following packages will be built and installed:
    glew[core]:x64-osx
Starting package 1/1: glew:x64-osx
Building package glew[core]:x64-osx...
Expected output of the form [hash filename
] (3 tokens), but got
[<hash>  /<snip>/test build/vcpkg/triplets/x64-osx.cmake
] (4 tokens)

the test build folder contains a space, and this throws off parse_shasum_output in vcpkg/toolsrc/src/vcpkg/base/hash.cpp
