Avoid multiple PREFIX definitions
The short and sweet PREFIX can be confused when used in many places. Rename both usages to better describe their purpose. EXEC_CMD_PREFIX is used in full to disambiguate it from the nearby GIT_EXEC_PATH. The PREFIX in sideband.c, while nominally independant of the exec_cmd PREFIX, does reside within libgit[1], so the definitions would clash when taken together with a PREFIX given on the command line for use by exec_cmd.c. Noticed when compiling Git for Windows using MSVC/Visual Studio [1] which reports the conflict beteeen the command line definition and the definition in sideband.c within the libgit project. [1] the libgit functions are brought into a single sub-project within the Visual Studio construction script provided in contrib, and hence uses a single command for both exec_cmd.c and sideband.c.
