[libgomp, testsuite] Double libgomp.fortran/vla8.f90 timeout factor

[Rainer Orth]

The libgomp.fortran/vla8.f90 compilation times out for me on many
platforms.  E.g. on an 250 MHz R10k Onyx^2 running IRIX 6.5 ,
compilation takes between 2:30 and 3 minutes, so for a parallel make
check it can easily exceed the default 5 minutes (300 s) timeout.

The following patch works around this by doubling the timeout and allows
all libgomp tests to succeed on mips-sgi-irix6.5.  Another option would
be to declare the test as expensive (dg-require-effective-target
run_expensive_tests) and not run it by default.

Whatever solution is chosen, something needs to be done here.

Is the following patch ok for mainline (and the 4.4 and 4.5 branches
after testing)?

Thanks.
	Rainer
