tests/unit: fix object files' location
Referring to *.o files under a .libs/ directory is not recommended
because this belongs to libtool's innards.
Indeed, libtool decides to place the *.o files in an
implementation-specific location:
- PIC *.o files go into a .libs/ directory;
- non-PIC *.o files are generated along side to their corresponding
source files.
Using PIC objects to build executable is legit, thought it may
introduce some minor overhead at runtime.
However, hard-coding these PIC object files in the Makefile.am to build
executables breaks the build in case of static only build.
In this case, no PIC object files is generated, so the linker will not
found some of the needed objects files.
Changing these dependencies' path fixes the static build, keeping the
shared one ok, though the non-PIC object files are now always built.
Fixes #983.

Tests: Switch test apps to use usleep_safe()
usleep_safe() ensures that usleep honors its timing guarantees
(which it, according to the man pages, does not strictly enforce).
Some tests need to make ensure no events are emitted at the same
timestamp since Babeltrace does not define an ordering which can
be relied upon in such a case.

Fix: lay out names in exclusion structure correctly
This:
char names[0][LTTNG_SYMBOL_NAME_LEN];
means that accessing
->names[0][i]
will return the i-th character of the first name.
So doing:
lttng enable-event -u -a --exclude hello,a,b,c,d
lttng save
would result in a saved session XML file containing
this:
<exclusion>hello</exclusion>
<exclusion>ello</exclusion>
<exclusion>llo</exclusion>

<exclusion>o</exclusion>
