[PATCH] selftests: exec: make binaries position independent

[Muhammad Usama Anjum]

The -static overrides the -pie and binaries aren't position independent
anymore. Use -static-pie instead which would produce a static and
position independent binary. This has been caught by clang's warnings:

  clang: warning: argument unused during compilation: '-pie'
  [-Wunused-command-line-argument]

Tested with both gcc and clang after this change.

Fixes: 4d1cd3b2c5c1 ("tools/testing/selftests/exec: fix link error")
