rsyslog: fix some of the ptests

Run test as non-root 'tester'.
Add more rdepends for ptest.

Introduce a patch to skip checking for a libc header:
    sys/inotify

Python scripts no longer called with ./script.
Remove the need to add the correct shebang.
Ptest results:

    8.2102.0
===============
TOTAL: 424
PASS:  417
SKIP:  5
XFAIL: 0
FAIL:  2
XPASS: 0
ERROR: 0

Remaining failure related to relp:
* imrelp-tls-cfgcmd
* sndrcv_relp_tls-cfgcmd

the test expects an error "relp connect failed with return 10031",
but the connection seems to be established and working.

+Subject: [PATCH] tests: disable the check for inotify
+
+We don't need to check inotify.h.
+Assume it is present since it is part of the linux kernel
+since 2.6.13 [1].
+
+[1](https://kernelnewbies.org/Linux_2_6_13)
+
+(it would require installing the libc headers otherwise,
+ for the test  to detect /usr/include/sys/inotify.h.)
+
+Upstream-Status: Inappropriate[OE-specific]
