util: add fault injection of EIOs

This patch adds the functionality to inject EIOs in env_posix based on
a flag-specified glob pattern indicating which paths should fail
and a flag-specified double indicating how often these failures should
occur.

A similar flag inject_io_error is replaced coalesced into the latter
flag, and wrapper macros are updated to ensure the returned error
expression is only executed when necessary.

A test is added to env-test.cc to verify that EIOs are successfully
triggered by specifying the patterns.
