Use $PATH when starting $SHELL 

If $SHELL is set to "bash", previously awesome failed to restart itself, because
it could not find "bash". This commit makes awesome use execlp() instead of
execl() which means that $PATH is searched if the started command does not
contain a slash and this problem is fixed.

$SHELL is specified in POSIX and it doesn't seem to require an absolute path
name.
