Previously changed mem_test (!10320) introduces a test which checks for
the value of `__FILE__`, which is different if the build is done
out-of-tree or not, even though this is not relevant for the test (only
the base filename is). This result in a broken test for out-of-tree
builds. Fix this by changing the way the "grep" is done in the test,
ignoring the optional path prefix in the filename.
/*
* Find the allocation of ptr and make sure it contains "[...] 2048 file
- * mem_test.c line [...]"
+ * [...]" (the "grep" is done in 2 phases because the prefix of the path
+ * of mem_test.c will change if test is built out-of-tree)
