action: implement exec() test option
Exec() adds the ability to run a command, with the
result of the test being the exit status of the command;
if the command returns a valid exit status (0), exec() returns
TRUE, otherwise on a bad exit status exec() returns FALSE.
Three environment variables hold:
- NAME: name of file
- PATHNAME: pathname of file relative to squashfs root
- SOURCE_PATHNAME: the pathname of the file in the source
directory
Currently only a single argument (without spaces) can be entered
as a command, this is because the actions parser currently lacks the
ability to have arguments with spaces in them (either argument quoted
with '"', or spaces blackslashed with '\')!
