update_desktop_file_entry: initialize return value properly, and actually return it

Since 1.4.4 (commit 75cfd97f) this function always returned FALSE. As far
as I can see this was actually harmless, because both of its callers
ignore any error that is not NoMemory (and treat it the same as success).

Add and use DBUS_TIMEOUT_INFINITE and DBUS_TIMEOUT_USE_DEFAULT

The documentation claimed that INT_MAX (whatever that means) meant the
default, but the value that has actually always been checked for is
0x7fffffff (aka INT32_MAX on the competent platforms we sadly don't
restrict our portability to), so we should use that. (In practice D-Bus
probably never worked on platforms where int wasn't 32 bits, though.)

installcheck: don't run installed tests against installed library if in a DESTDIR

That probably won't work, because it'll find the system-wide library
which might be older.

Alter test-dbus-daemon so it tests the installed dbus-daemon by default

For installcheck, adjust it to use things from DESTDIR.
