[PATCH] kselftest/alsa: add silent flag to reduce noise

[Abdul Rahim]

When ALSA is not installed on the users system, the error:

"Package alsa was not found in the pkg-config search path.
Perhaps you should add the directory containing `alsa.pc'
to the PKG_CONFIG_PATH environment variable
Package 'alsa', required by 'virtual:world', not found"

is printed 3 times, which generates unnecessary noise.
Hence, Remove unnecessary noise using `--silence-errors` on LDLIBS
assignment, so the message is printed only once.
