t1450-fsck: exec-bit is not needed to make loose object writable

A test case wants to append stuff to a loose object file to ensure that this kind of corruption is detected. To make a read-only loose object file writable with chmod, it is not necessary to also make it executable. Replace the bitmask 755 with the instruction +w to request only the write bit and to also heed the umask. And get rid of a POSIXPERM prerequisite, which is unnecessary for the test.
