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.
